Point being entshittification comes at a cost, and companies partaking in shitty activities can only keep this up for so long.
I think their strategy is to poison the internet so thoroughly that no better search becomes possible. The costs alone to spin up a new search company are an enormous barrier to entry, they'd only need to erect a few more to make it impossible.
I do think the dynamic there is still a bit different from where the term usually applies, since advertising involves three parties in addition to the middleman, not just two -- the above comment was looking at things from the perspective of end users, in terms of where they prefer to watch videos, and that actually may represent a constraint on how much "enshittification" can happen that's particular to this industry.
They're literally the middleman between layfolk an the Internet itself?
Check the list of companies they've acquired, divisions they've divested, random research they're doing. While mainframe is a big portion of their revenues (depending on year), they're super diversified.
Intel never managed to leverage its dominance in x86 CPUs into dominance in other markets though, and that is the key difference to the ultra-large companies I mentioned... yes, they did have ARM offerings (XScale, I 'member tinkering with an NSLU2 decades ago), they did have a cellular modem line (that failed and got sold to Apple eventually), they still do have the Intel Wireless lineup (which is pretty widespread but has a healthy competition), and they got a decent dGPU lineup that nevertheless is at, what, 1% of market share?
And that is what is screwing over Intel at the moment. The server CPU market is going down the drain, gaming consoles went to AMD, Apple is completely lost as a customer (thanks to Intel's various fuckups) and consumer device demand is shifting to phones where Intel has absolutely zero presence. And on top of that their fabs have fallen way behind plan - to think of that Intel has to go to TSMC? How far the mighty has fallen.
For example Thorn used to be massive in the 80s and by the end of the 90s it had ceased to exist. Arqiva is another that’s presently in freefall despite previously being too big to fail.
Also, I dont really think you can accuse IBM of a lack of diversification.
