They're late to the party. The canapes have been consumed, the beer has been drunk and everyone's down to that miscellaneous yellow dip and the leftover breadsticks. Zoom has won, Google, with Teams coming in a respectable 2nd place. No-one's got any reason to use your product.
Google Meet is late indeed, but might gives some peps. It’s already a crowdy market - you forget to mention Messenger as well as some startups. Zoom has taken the lion’s part - apparently - but that’s very fragile share. Users jump from one service to another for many reasons (network issue, I’m used to X, let’s try Y, etc.)
Only the ones with the more beers will be able to stay.
