It's a hard call on Reddit.
This article seems to leave out the reality that Reddit's big win is data and an in built machine learning capability in what is good quality. For future AI and LLMs it's actually a treasure trove of information that will only rise in value.
Realistically it's had massively bad PR and issues but people still use it over Lemmy and many others, and Lemmy/others aren't going to overcome it any time soon (if ever). So it doesn't seem like it's going to go away at end of day, and it's still one of the best sources of information on the internet available.
At end of day it's stocks so it's coin flips all the way. No one beats the market consistently over time that doesn't also utilise insider information.
