I’m fairly new and don’t 100% understand it yet, but instances are run on servers that require money. Are we heading towards seeing ads or subscriptions to raise funds instead of relying on donations to cover overhead?
Especially with the influx of new users. Hardware upgrades are needed.
That depends on how the admins decide to run their instances. After several crises and dramas, etc., I can say that those who decide to monetize eventually will; but so far people have been supporting their admins through crowdfunding.
The really big instances are deciding to be open to Facebook in exchange for big money. A lot of folks in other instances don’t like it, and some instances have already decided to defederate from them in advance (search for the hashtag #FediPact). Yes, there’s lot of drama involved.
