Yes, but also it’s not an employer’s job to provide entertainment during work hours on a factory floor where there are machines that can kill you if you’re not careful.

There’s a famous fable where everyone is questioning the theft victim about what they should’ve done and the victim says “doesn’t the thief deserve some words about not stealing?”

Similarly, it’s a corporate network designed and controlled for work purposes. Connecting your personal devices or doing personal work on work devices is already not allowed per policy, but people still do it, so I don’t blame network admins for blocking such connections.
