Solo play is still online play so you're still contributing the same as anyone else. I've done community goals in private group/solo before and never had a problem. I rarely play in open and the only people who are bothered by this seem to be the same people I'm trying to avoid via solo/private in the first place.
Just tried this on Android Firefox with blocking via Pi-Hole and it's working fine for me.
Yes, I manage my Raspberry Pi Plex/Pi-Hole/OpenVPN server using command line because, well, it's Linux.
Also for work I manage Windows Server based systems and although this is a largely GUI based operating system, Command Prompt/Powershell are still tools I use daily to provide more control and depth over what I can do (bulk admin actions, for example).
I don't really use command line out of preference - moreso because it's the necessary tool for the job.
Fantastic photo! I moved to Lincoln as a student and have lived there ever since. It's a beautiful city!
I see where you're coming from but I think it depends on the games you're playing. I think Deep Rock Galactic and BattleBit Remastered are two examples of games that are pretty fun and refreshing. I've made a lot of memories with my friends in both games - particularly BattleBit, which is an absolute blast.
