Oh i think its a perfectly legitimate and reasonable reaction to new Twitter management. a guy worth about 200bn USD spent his first day at the office dragging a piece of plumbing around cheerleading his impending job cuts and upcoming $8 surcharge for a feature that only really benefits and legitimizes the platform. he then axes most of the company, especially the moderation team, and acts shocked when brand-safety conscious corporations pull their advertising out of an abundance of caution.
hes lucky corporate brands and advertisers havent figured out they could start their own Mastodon instance for almost nothing, plug it until it becomes more popular than Twitter, and maintain all their existing brand safety controls in the process.
If Musk wanted to take a 44bn USD kick to the knackers and spend the end of his year getting deadass roasted on his new social media platform by literally everyone, its a success.
