Thanks for the follow-up.
Working from memory (which for me is perilous) when I first started paying attention to Brave’s Muon version, this issue — user control over updating — garnered some enthusiastic support from users but was summarily dismissed by Brave.
I added my support to the earlier thread and to this one to prime the pump.
With essentially no call from Brave users for control over when and how Brave seizes and uses resources, the only viable alternative is self-help and workarounds like editing autoruns.
