This whole episode is giving me flashbacks to the ActiveX days.

The tyranny of the default.

“Here mum, I’ve installed Firefox for you, it’s better than Chrome in every way!”
“My knitting circle website doesn’t work, I can’t download patterns, it says I need Chrome”

Internet Explorer was effectively abandon-ware for a decade after Microsoft used their OS pseudo-monopoly to crush Netscape.
It took another tech giant abusing THEIR monopoly to relegate IE to the trash heap it should have already been on.

Comforting and Terrifying.
Comferrifying?
Terriforting?

So you won’t use your banks website?
Or your utilities (gas/water/electricity/internet)?
You won’t let your kids use the portal at their school for submitting assignments?
Your government sites for renewing your drivers license or scheduling hard refuse pickup?

I can think of lots of reasons that will force me to have chrome installed if this goes ahead.

The Back to the Future trilogy is good for a re-view.

The condescension in that makes it clear that the smug social network is whichever one the author happens to use.
