1. Frans Pop was heavily involved in Debian
2. The suicide took place in the same week as Debian Day
I find this very unconvincing. I don't know much about this situation, so I'm not going to say Debian is 100% innocent, but the evidence the website provides is one (irrelevant) post from a mailing list.
I don't think the website does a good job of laying out the details in a clear manner and has a definite bias, but your summary seems deeply flawed.
Please link to me anywhere the website substantiates any allegation/claim about Frans Pops past the ones I listed with any level of evidence at all (NOT unsubstantiated speculation) - I genuinely cannot find it.
