Sounds like what I need is a VPN or Tor in these cases. To such regimes if FF provides a way to bypass their restrictions FF would end up being classed contraband similarly.
But DoH makes the price of blocking a single domain too high, for example, if Cloudflare were to use it, the only way would be to block every service that uses CF.
Overall, this will have an impact in the many regimes- and perhaps is one of the best methods of doing so. While it is still ...having faith in Cloudflare(one could audit them, but of course the question is how by-nature are they built to resist threats from APTs to the US gov coming knocking for info on Snowden or a similar person, looking for possibilities of compromise) -
I think of the Ukraine Starlink situation- Overall, the Starlink terminals can be targeted by their signals, - but there's so many ,that Russia would need to do a massive ASAT campaign, or start spam detonating kiloton/megaton warheads in space to really try to disable Ukraine's ability to communicate even when all other networks get cut off, or isolated. And they mgiht be one of the very few capable of that type of escalation, but right now they're getting stymied by groups that are en - masse, accessing something that makes it harder to control, deny info, influence and crush them.
Overall a net positive, but with drawbacks- but their overall situation and ability to choose how they want to operate is increased.
VPNs and TOR are gaining popularity, but this covers those who wouldn't be able to use or figure out those for whatever reason, but who can use a web browser. I think i've seen the Cloudflare CEO around - i wonder if any cloudflare employees will comment on the risks i mentioned before(centralized source providing availability, US GOV deciding to take interest...)
Firefox actually can solve this- by attempting to pursue deals with more than Cloudflare and NextDNS
