From my point of view, I prefer to assign errors to either stupidity or cluelessness rather than malice, and this -- relatively quick -- response makes me hopeful that Patreon understands its mistake. The questionnaire that they link to in that post encourages that view, as the choices clearly echo most of the major issues with their policy change.
I really hope they HAVE learned the real lesson here, because -- speaking honestly -- this is the ideal platform for the purpose. There IS no really decent alternative, at least not yet, and while I know people are talking about making new Patreon clones, etc., I am not terribly confident that some new group would be any LESS likely to make bonehead moves. They would be DIFFERENT bonehead moves, but make them they would.
At least Patreon appears able, and willing, to recognize mistakes and listen when the reaction is clear. That's more than many companies.
