To be clear (because I was confused at first), the creator in this context is an instructor of an online blender class, not a contributor to blender itself.

Wait one pronoun? But cis people are typically he/him or she/her each of those groups have 2. Strictly following that rule only people allowed should be "any" or "gender fluid" right?

I get this is horrible and hateful but I would totally go nuclear strict compliance. The person most likely meant "you can only ask to be referred to by one set of pronouns" but he said "one pronoun".

"I made a picture for my mother and she liked it".. Banned she and it are both pronouns. "He taught me that feature" banned he and that are pronouns. "we are reviewing this bug report" banned we and this are pronouns.

These people don't seem to even know what pronouns are.

Go ahead and speak normally without using I, me, you, them, they and it.

Constantly refer to the instructor as a she. When corrected, push back and call them “snowflake woke pronoun warriors”

People should put random pronouns into their bios, then speedrun bans.

There is only one pronoun choice!

Dude.

I'm a dude, he's a dude, she's a dude, cause we're all a dude.

But fuck that bigot.

Sees profile pic and name thinking... "Is this blender bros??"
It is blender bros...

Well, if the OP really want, they can get a few courses on the high seas.
I suppose blender bros courses are made well enough and popular enough for someone to "distribute" them.
