Reddit is making the same mistake that 3DFX made against Nvidia and ATI back in the day with third party developers. Restricting 3rd party development was suicidal on reddit's part.
Ultimately, people want choices, and I think if the average user see only one reddit app vs a literal wall of different Lemmy apps, they will be inclined to try at least one Lemmy app instead.
I disagree that the majority of people want choices, at least when it comes to social media. The vast majority of social media users want to be where the user base is at. For Lemmy to be the more attractive option, it either needs to have do similar numbers to it’s competitor or offer something very unique and useful that the others don’t.
And I say this as someone who has been much happier on Lemmy than I have been the last few years on Reddit.
