I think Gab [1] is a relevant example. They were dropped by their GoDaddy, Stripe, PayPal, etc. after the tree of life shooter posted their manifesto on the site. Another example would be Cloudflare dropping 8chan [2] after the El Paso shooter, Christchurch shooter, and Poway synagogue shooter used the site to post their manifestos. Cloudflare also dropped support for the neo-nazi website The Daily Stormer [3] although my impression is that the reason for termination was deeply related to people on the website claiming their continued business relationship signaled ideological sympathy on the part of Cloudflare [4 -- about halfway down]
