They’ll jump if they want to. If it’s any consolation, the dev for Boost (my Reddit app of choice before everything went down like it did) announced that he was going to make a Boost for Lemmy after commenting that he wouldn’t. Perhaps the Infinity dev will come to a similar conclusion?
It looks like the limit is on reading posts, not posting itself. It’s way easier to read that many posts, especially if you’re glued to your phone and scrolling past dozens of uninteresting tweets at a time.
That being said, this limit is likely in place to stop web scraping or some such workaround to the need-an-account-to-view-stuff policy.
As someone who never got to experience the web as so many remember it (before it became centralized and primarily monetized), I’m quite excited at the prospect of Lemmy and the Fediverse in general. Maybe my generation and those to come can come to know a better internet.
