Did they ever clear up their more-than-doubtful claims about their relationship with Cloudflare?

They recently claimed that "Even when we’re under attack, we still don’t use their TLS certificates, so Cloudflare will NEVER content inspect our traffic."

Cloudflare DOES NOT offer a passthrough-TLS option.

This was pointed out with no response which makes me doubt more than just their technical abilities...

Cloudflare offers at least two options that don’t require them to proxy TLS: Spectrum and Magic Transit.

I am reading the following in the link you posted:

When we’re under attack and using their proxy, Cloudflare can, unfortunately, content inspect our traffic.

I think they may have edited the post.

My account was frozen due to being flagged as spam. But I got some fine stickers. ActivityPub FTW :-)

Why does everyone on the timeline seem to have the same exact beliefs, opinions, viewpoints, and style of expression? What a colossal bore.

Just have a look at their COC.
