While you're correct, what they "left" is actually a non-programming legal foundation (other than Sawyer X), and so the commenter is actually correct that this ultimately does not have the impact on the Perl community that the article suggests.

Those itemized (and the two people who also left TPF roles who have not been listed) only left their TPF committee positions, and not their programmer roles. Sebastian even did another Mojolicious release this weekend, and his presence on the libera#mojo channel has not changed.
