According to the article "hundreds" of experiments showed an effect. Then it goes on to talk about the reproducibility crisis, but in this case it has been reproduced, no? At least, that's what the article itself says.
Link to actual debunk study is dead, but "it now appears that ego depletion could be completely bogus" seems too strong. Certainly in my own experience something like ego depletion is very real – maybe not exactly as described, but you do run out of bandwidth at some point, so to speak. One of the reasons this is hard to verify experimentally is that, in my personal experience, everything is fine up to a point, after which it all breaks down. You can't easily re-create that in an experiment.
The Wikipedia page has a pretty good rundown on the criticism and existing studies. From my understanding, it isn’t clear that the studies that have been done indicate any depletion effect at all.
