I've been working remotely in game development for 10 years. A highly collaborative field. Requiring artists, producers, engineers, designers, QA, and marketing all communicating across levels. Meaning junior designers need to talk to lead engineers and everyone wears many hats.

You are completely correct. In fact, zoom is a terrible system to use. I highly recommend no one use it for remote work. Use Google meet, discord or mumble for persistent voice and video. Use slack, discord, or teams for text. Use Google docs or confluence for document sharing. Use trello, Asana, jira, or hacknplan for task planning. Use Miro for idea boards.

You need a full suite of services but not in a single field would I recommend zoom. It's such a bad piece of software that I'd literally recommend jitsi over it.

This is probably why they are returning to the office. Their software is so bad they'd have to use something else to be productive and the best way to save face there is to say that your software isn't unique and that no software can replace physical offices. In reality you have full business that have been remote for decades without problems. Business that require far more collaboration than zoom.
