Are you familiar with the concept of a captive market?

Its only freedom if there's actual choice involved.

The scale at which these sales are made has nothing to do with the average consumer. Its just mega corps crunching numbers.

And that really only has to do with share prices, none of it trickles down to the actual workers.

This is just rich people having slap fights.

The problem with that is when a company like Microsoft has used and abused its position for such a long time that the only possible competition is another megacorp. No real choice there, only an illusion of choice.

this is all well and good when we're talking about a properly elastic market (eg food)

however, the supply of hosted enterprise video conference software is extremely limited (teams, zoom, google meet) and the demand is extremely high

moreover, switching providers and reeducating the staff will also be highly expensive

you can't exactly go anywhere else, you just have to agree to whatever msft is doing
