Possibly. I’m not sure how true it is that the fediverse necessarily leads to more efficient computing needs per user. I’d bet it’s the opposite.

But, as you perhaps allude to, there are other factors. For those who only want niche smaller communities, they can enjoy a more stripped down experience without needing speedy and beefy servers. Similarly, the platforms here are probably slimmer and not bloated with features that are trying to engage and monetise.

The major factor, IMO, is ownership. Admins literally own their servers. And should have a much closer and codependent relationship with the users in their servers, except in the case of large instances which become different beasts. Additionally, users have much more choice and mobility on the fediverse. All of which means admins/moderators and users have more at stake in their relationship. More ownership over their platform/instance. And therefore actually have a reason to donate and contribute and help out.

In the interest of fairness, isn’t the difference between TenCent and the Chinese government basically just paperwork? I’ve always heard (anecdotally) that they work extremely close with the CCP.

i don't know if i'd go that far? with Tencent specifically it is inarguable they have worked with the Chinese government on some things and that's not nothing. but Tencent is still an independent company, and governments and corporations/their shareholders frequently don't have the same interests at heart, so it's hard to say where to draw the line here.

i think my position would be: i don't think it's useful to assert everything they do is intended to advance what China wants, especially in the absence of anything indicating that. i also don't know how useful it is to assume they're just a front for China--certainly i don't think that the people most vocal about this consistently apply that concern to other countries like Saudi Arabia who use companies to advance their state interests all the time.

conversely, i think it's ridiculous to confidently assert Tencent have never, or don't ever, get influenced by interests China has, or that Chinese state officials aren't capable at least theoretically of using the company to advance state interests. that stuff happens here, where ostensibly our system exists to prevent that kind of collaboration (this is basically what the "military-industrial complex" is, for example).
