It’s a fact:
The same Apostolic Delegate who approved “passive membership” in the Freemasons for Americans also wanted you not to do penance on the Friday after Thanksgiving.
Signs of the times, as Mithrandylan once asked?
Nobody's stopping you from doing penance, but the issue is whether or not you're going to impute sin to those who decide to eat meat that day ... just like on your modesty thread. At another point, you claimed that dispensations and relaxations of law like this are invalid because they're against the common good. In that case, you really are required under pain of sin to fast on Wednesdays also, because that was the mandatory practice in the early Church. For that matter, you need to be keeping the fast all of Advent just like in Lent, since that too used to be the Church's discipline, and so the relaxation of that was clearly invalid. You should start a website to denounce all the lax Catholics who do not fast on all the weekdays of Advent like they used to in the good old days.
