Fair enough if you don't want to donate.
Your BP analogy is a bit strong, no? It's not like removing and then reinstating the Thanks button has actually damaged anything unlike a giant oil spill in the ocean. Also you will note that BP has not corrected their mistake, unlike SB I always thank people for making amends for something that they have done wrong.
It's not about donating or not donating Sas. It's about the OP's pretense that if you correct a mistake, somehow you should be rewarded. Personally I think this is ludicrous, but that's just my opinion. If people want to give any amount to SB, that's great! If the reason for the donation is because of a corrected mistake, I think this sends the wrong message. If you are donating because you want to help defend the lawsuit, this is an entirely different reason from rewarding a business for making an error. Just saying.
