One of the founders overdosed, they switched hosts, and overall seem to have done everything in their power to tank themselves.

No? I don't think the comment implied that; I separated the two between an "and" for a reason. I was just stating that that was when things seemed to start going down for them.

I think it's clear that it's not the intended meaning, but I can see how it might be misread as that. "and overall seem to have done everything in their power" did make me wonder for a brief second if the first two things were examples of things in their power. Personally, I'd probably tweak it to something like "and overall seem" to make the distinction more clear.
