I really appreciate the clear explanation in this graphic, but I don't understand why you would include the trash-talking of linux-libre at the bottom.
If you cut out the unnecessary part about linux-libre/BSD/Alpine, then I think you have a very nice graphic that might help more people understand the issue.
Don't say that linux-libre is garbage, that is simply not true: linux-libre is what it is, and depending on what someone wants it may or may not be useful for them.
