"Lots of people in Twitter" doesn't sound like proof to me.
What is acceptable as proof to you?
Peter Todd is talking about OUTPUTS being reused in coinjoins
He talks about both inputs and outputs. For the former gives an example of an entity which has received multiple donations in the same address (and which I agree with), and for the latter when an entity wants to make multiple donations to the same address (which besides unusual, is just not what the front end displays as an option). There are quite a few reports of Wasabi reusing receiving addresses when automatically coinjoining, and none of the victims wanted to donate (otherwise they wouldn't report it as a bug).
BTW, why do you keep posting this video? Peter is also okay with Wasabi censoring inputs as he says. Being a Bitcoin Core developer doesn't grant you any ethic superiority. He's sponsored by Wasabi, and is being paid by Wasabi. Why isn't he considered a "shill" like you claim us to be with mixers?
