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.

I’d sign up to Titter.

Individual instance owners can do literally whatever they like.
Put up ads.
Charge a subscription.
Anything.

Let’s say instance A is hosting a community that everyone on instances B and C love to participate in.
But A want’s to earn some money so they start charging access to their local users.
This doesn’t effect users of B and C at all, because the data is federated.
The owner of A get’s grumpy and defederates B and C.
The users on B and C find somewhere else, either on one of their instances, or on D.

Everybody wins.

I also use this.
Have had to update it in tiny ways in the last ~ 7 years?

The issue was the owners choice of not federating with anything nsfw.

By moving to lemmy.world I could still post as much as I wanted to !australia@aussie.zone AND upvote boobs.

I moved from aussie.zone to lemmy.world already to get around federation issues.
Now beehaw.org has stopped federating with lemmy.world 🤷‍♂️

I don’t want to have half a dozen accounts so that I can access all the niches of this system, and yet it’s beggining to look like the dream of federation is stillborn.

Absolutely possible.
The key to simple self hosting is to have a dns record that points to your externally accessible IP, whether that be your real one or an external one hosted at a VPN provider.
If that IP changes, you’ll need to update it dynamically.

It’s becoming increasibly common to be a requirement to do so as CGNat becomes more widespread.

One of the newer ways to do that is with a Cloudflare Tunnel, which whilst technically is only for web traffic, they ignore low throughput usage for other things like SSH.
