For us, teaching children online, the cost of switching would be huge.

I was on the team that chose zoom (which I now have reservations about, but that horse has bolted).

During the initial discussions, Google dropping products was brought up and was our primary reason for not picking their product.

Strongly agree. It seems every few months or years the tide shifts and we all move to something else. And one may use different choices for different groups or larger or smaller audiences.

No need to emotionally invest.
