About half the team share similar view. The other half seems like just playing along.

The “other half” is culturally fit for a large company.

I still care about the mission

Missions require full commitment.

Then by the will of higher ups some teams got drastically reorged and I ended up in a different team with a new manager.

That’s the nature of change.

Good luck.
