There was an old proverb; something along the lines of "don't curse anyone that's already 6 feet under, no good will come of it".

I just don't think people should pretend to have liked him or been friends with him only after he parts. It seems disingenuous to his actual friends and people who knew him personally.

I think there are a few cases where individuals should be able to hold grudges against dead people (see Jeffery Epstein as a great example here); but I believe Techshare is less evil than Epstein.
