Did you know you pay more fuel tax on a single car journey than a billionaire does on a private jet flight?
Right now the gov is subsidising tax breaks, when they could be using that tax to generate billions for public services.

The government spends £2.7 BILLION a year on TAX BREAKS for oil and gas companies
Those companies pay billions to their shareholders
And then lay off their workers
Think that's unfair?

In short, the problem here is not that Signal ‘chose’ to run on AWS. The problem is the concentration of power in the infrastructure space that means there isn’t really another choice: the entire stack, practically speaking, is owned by 3-4 players. 11/

Military emissions are excluded from national emissions figures. Yes, we simply pretend they don't exist.
