I love all the replies on Twitter thanking her but during her time the valuation dropped 80% and they were suing advertisers for not advertising. Remarkably inept.
Anyway she volunteered to be a puppet for a man who is clearly off the rails and her legacy will forever be stained.
Therefore the praise is weird, because she seemingly neither helped nor hurt the business.
Fall guys bear some of the blame in the fall.
My long-held [0] personal theory - borne out by everything Musk has done, and by who bought Twitter - is that it was bought to curb the possibility of large positive social movements along the lines of OWS or BLM.
Enabling that can entail being useless at your supposed job, while doing your actual job (which deserves some amount of blame, from a number of perspectives).
History has shown us, the more you try to control it, the more it slips through your fingers. The best surfers know, you ride the wave, not fight it.
