I see you have been paying attention. Past behavior is the best predictor of future behavior, so I would say your prediction is right.

Finding advertisers, billing advertisers, and collecting from advertisers is all work you can avoid of your users just give you money.
I've been chipping in for my mastodon server for over a year. The admin there posts the finances so we all know when it's time to kick in again, but if we went to a paid rather than donated set-up, then I'd be OK with that. If my admin decided that he needed to run ads that were like printed newspaper ads then I wouldn't mind so much. But ads that track me, ads that change size, ads that show up and block some or all of the screen, ads that play video and audio, pretend to be content etc are the ads I dislike and I would flee.
OK, true, but that's why they want to charge 3rd party apps.
Ehh, if Reddit is getting traffic from people going to see the trolling, then Reddit is still making money.
Knot tying is a handy skill and easy to acquire. All you need is a short length of rope and watch a few videos. There may be thousands of knots you can learn, but most people should take the trouble to learn a few tried and true knots. Maybe you want to move a mattress on the roof of your car. Maybe you want to tie a pen to a clipboard. Maybe you want to tie back the legs when roasting a turkey. Maybe you need an impromptu collar & leash for a stray dog. Maybe you have to move a huge bundle of brush you've cut. Maybe you want to tie neat looking stopper knots on your hoodie's drawstring. Knowing how to tie a few different knots will give you options when you're trying to get stuff done.
It doesn't have to be impeccable. It doesn't need corporations to buy ads. It just has to keep getting better and not die. Look at Linux. It never did overtake MacOS & Windows on desktops. But it keeps getting better and it didn't die and it took over server rooms. Look at Mastodon. It's nowhere near as popular as Twitter and maybe never will be, but it's 5 years old and is steadily growing. I like hanging out there. Oak trees start as acorns.
I don't want to see ad-supported instances. If you like using an instance (pixelfed, mastodon, bookwyrm, kbin, lemmy etc.), chip in. Keep the fediverse free from ads.
How do I kick in to pay kbin.social costs?
Jeez, I'm on kbin.social, ramblinreaders (bookwyrm), pixelfed.social, and dmv.community (mastodon). So far I have persuaded 0.0 of my Instagram and Facebook friends to move to ActivityPub instances. :-( Might just be me. I've stopped posting on the facebook except for a quarterly post about Mastodon and I deleted my Twitter. I don't know how fast Insta will reach terminal enshittification, but it seems to be holding on.
You can spread powder on the floor so you could see if someone had stepped in. It wouldn't keep them out unless they didn't want anyone to know they'd been in there.
