It may be temporary, but if bringing back X improves the quality of someone's life, more power to them. We're stuck with the downsides of continuous delivery; having a consistent UI for just a bit longer can be a cognitive relief.
When Pixel phones switched from navigation buttons to gestures I tried them and hated the experience and reverted. Eventually I got forced over to gestures and still hate them so delaying gave me a bit more bandwidth to allocate from stupid UI changes to things I actually care about.
For offline things, I agree - the people keeping older versions of Photoshop working, for example, are getting plenty of value and saving money.
For a network service, however, I think this is worse than doing nothing: continuing to use Twitter at this point is not neutral but actually supporting and rewarding Musk for every decision he’s made, and your use of a social network encourages people you know to stay there. That means that you’re not only not finding a long-term replacement, you’re making it harder for one to exist.
