Yeah for sure, usually if it doesn't "just work" or if its not convenient or they just "don't want to" then it'll be hard to convince anyone, getting all my family to move from standard SMS to signal was hard, there was no real barriers yet it was still too inconvenient to switch, even with all the benefits it offers. The two biggest issues I've seen so far is the "sub-lemmys" or just communities that exist, multiple similar communities can co-exist and have separate users, which isn't good for growth. The second issue, and by far the most worrying currently, is performance and stability with the instances that currently exist. Already we're seeing the main lemmy.ml instance being brought down to its knees with all the new users. If reddit doesn't reverse their API decision by the 12th (which at this point seems unlikely considering all the backlash already with no response) then I can't imagine how bad it would be to see even a 10th of current active reddit users trying to join at once. Its an ticking time bomb with a very quick expiration date if its not addressed quickly. I do have hope however, although my programming experience is somewhat limited a threw a few bucks on the opencollective, which I suggest everyone do if you wanna contribute in some way and you believe in the idea of a more open free internet, circa the late 90s.
