How do you explain several non-EU states being members of the Galileo programme - namely Switzerland and Norway? Hell, even China invested into it in 2003. And yet, the UK which invested almost a quarter of its funding is booted out on the basis of an unrelated political issue? It doesn't make sense. The British even offered to continue funding and investing into it. So "forced out" is an accurate description.
The UK were in because of their EU membership. No one could have taken that from them besides they themselves.
And once you are out you get treated like any 3rd party state. If you want a special deal you better bring some time and be prepared to start fresh.
The desire "to get Brexit done" in a very tight timeframe, pushed by populist politicians, did not allow for that.
The whole deal of the EU is to make cooperation between countries easier and to act as a single voice.
The UK reaps what they sowed
The idea that there was not enough time to negotiate is nonsense. This was the EU punishing Britain for leaving, its as simple as that. If the EU was really about European cooperation, then they should have wanted Britain to stay in the project.
ESA existed before the EU and cooperation on space goes back way before the EU. It was short sighted politics with the goal to inflict punishment on Britain and make sure nobody else leaves.
That's just plain false. There was one major outage in 2019. Since then, nothing of note.

The first one is indeed significant, but to call it an outage is a stretch. You're linking to some blogspam that is basically [copying the official statement](https://www.gsc-europa.eu/news/galileo-nominal-service-resto...). To link that without linking to the [follow-up explanation](https://www.gsc-europa.eu/news/further-information-on-the-ev...) is, well... Not exactly an okay move. In that follow-up, you'll read that only ill-configured receivers (that ignored satellite health) were affected.
