Since the same technology and the same manufacturer is being used, it's a weird problem to have after the satellites are already in space.

All the satellites probably use the same clock power supply, regardless of which clock they chose to put into the satellite.
That would explain why you have the Indian clocks by the same manufacturer all working, and why two completely different clock technologies (hydrogen maser and rubidium) are both failing.
If they double everything they won't make this bad idea of sharing the same power supply.
After all, a global system has clear military value. In contrast the Indian system is limited in coverage to India and nearby nations.
Edited to add: also, the fact that Stuxnet was discovered would be good reason to think you wouldn't attempt this. You'd need to be bullet proof certain that it would never be discovered.
The Americans spent a decade and a lot of money on the first gen system in the 80s (we're on like the forth or fifth gen of GPS sats now) and the sabotage could be as simple as making it a classified state secret that mounting the physics package such that the electrodes are vertical causes microfractures in the physics package due to launch vehicle pogo resulting in 6 month lifetime on orbit, max. Or maybe mounting the physics package horizontally. Or it was spin stabilization that killed it or ...
Or you thought kapton would be a great plastic film for high voltage high temperature insulation for the physics package but (mumble mumble secret squirrel stuff here) as documented in classified air force memo #classified, insert finger wagging here oh no you can't get more than 6 months lifetime on orbit shouldda used teflon (or vice versa)
It could be as simple as a pdf that should have been posted to arxiv.org about some engineering peculiarity of Rb cells getting classified and buried. Maybe because it cost the US government a billion bucks to learn it the hard way back in the 80s.
Russia has GLONASS, China has BeiDOU, India IRNSS, Japan QZ
Russian GLONASS had full constellation in 1995, then during late 90s it had breakages, but was fully restored by 2011 again.
EU Galileo has full constellation planed for 2020.
Last year, the EU press spokesman for Galileo, Gilles Gantelet, declared that under the strain of American pressure, "Galileo is almost dead".
While US pressure has not killed off the Galileo project entirely, concessions made by European officials mean Galileo will now be a much weaker rival to GPS than the system they had envisioned.

Galileo will lead Europe into conflict with the US, which has security concerns about the building of a navigational network to rival its own system.

The United States has security worries about the development of Galileo.

As far as the fighting goes the Ukraine is negligible considering all the armed conflicts around the world.
It's probably just a mistake on the ESA's part -- space is hard.

The idea that there's a conspiracy at work is ridiculous. We're not exactly at the "Star Trek" stage of humanity here. Landing on Mars is still risky.
"NSA/NRO sattelite parked next to major Middle-Eastern telecommunications sattelite"
I say this as someone who likely subscribes to at least 20x as many conspiracy theories (defined as the existence of one or more people conspiring) as you do.
It may be "humanity's triumph" for you and me, but there are people who couldn't care less about that - people, for whom the only relevant thing is its impact on their political and economical standing. Such people are the ones who tend to find their way to positions of power.
† Again as a disclaimer: I don't have a horse in this race and I subscribe to a ton of conspiracy theories (way more than you). This is just not one of them.
At least Galileo is a competitor, and the political/military discourse about it is still ongoing.

However by reading the description provided it do seems more likely it's due to mistakes
Because things do behave differently "on production" and tests (and launches and space) do sometimes makes things worse
Most of the maser failures (5) have occurred on the satellites that were originally sent into orbit to validate the system, whereas all three rubidium stoppages are on the spacecraft that were subsequently launched to fill out the network.
Rubidium clock failures are being seen in "operational" Galileo satellites. First operational Galileo was launched in 2011.
And, first operational Indian navigational satellite was launched in 2013. So, there's not much difference in the timeline or aging of Rubidium atomic clocks between ESA and ISRO satellites.
Anyway, ISRO will be switching to indigenous atomic clocks for next generation navigation satellites[1].
