You can submit feedback to Slack using "/feedback" command. The nice thing it appears they have real people give you real replies. I encourage people to use it.
I asked them for the option to turn it off. An excerpt from their response.

It's like the answer to the second half is in the first half of their statement.
There are definitely several things that I don't like about Slack, but their support has been very responsive. I've reported at least two issues, and they have always taken my input seriously.
A while back, I reported a bug with copy/paste, and they asked questions, acknowledged it, and had it fixed by the next release.
More recently, I had a question about why the UI behaves in a certain way I didn't expect, and they took the time to explain that it was intentional, and what their reasoning was for doing it their way instead of how I expected.
All of these experiences are way better than average for our industry, which in my experience usually just brushes you off without trying to understand your issue and tries to placate you with a non-answer or answer to something other than what you asked.
I agree. Usually Slack's support is wonderful. But with this awful WYSIWYG input debacle, their support has been... subpar. A whole lot of non-answers and dismissive "we're collecting user feedback".
Just remember, the people who read and respond to you are probably not the people who either implemented or designed features and bugs you may run across.

I'll be sending this as my follow-up.
