I think it was from when someone posted on Twitter/X that Israel was just as guilty as Hamas for killing innocents and should not expect unquestioning sympathy and financial assistance from the US, and Elon replied, "True statement" or some such...

And suddenly, just like that (!) Elon is deemed Enemy number 1, and an 'Anti-S_e_mite by the J_wish-owned Media Matters 'watchdog' propaganda organization.

Then, Media Matters began a campaign to assert that Twitter/X positioned 'Nazi' or Anti-Sem comments or postings adjacent to the big name advertisers ads. Pressure to cancel was fierce and many advertisers cancelled after Media Matters produced fictitious evidence.

Soon, Elon filed a lawsuit against Media Matters for the libel, slander and tortious interference and has been winning more fans every day!
