No, it’s worse. The network filtering companies (which they appear to be using) sell “bad domain lists” primarily by arguing “we have more bad domains than our competition”, so it’s all a race to the bottom to include as much stuff as possible for as little cost as possible.

In this case, I assume the blocks are provided by https://talosintelligence.com/reputation_center who has a long history of totally nonsensical blocks and when you point out an issue they fix it then remove it a week later.

Never, ever, ever deploy a network with a commercial firewall vendor’s domain blocks.
