Brave does support opening tabs from other devices, sync works good so long as it always has at least 1 device in the sync chain, so if you only have 1 device and have to reinstall it the settings might be lost, but if you have 2 devices and reinstall one the settings are still saved whenever you rejoin the chain. The reason is there are no accounts saved in brave, so the only way to ID your browser is by the sync chain. If the sync chain has no devices it may be removed from the sync servers.
All of the crypto rewards stuff can be disabled with 1 switch, and a second switch if you also want to turn off wallet, but it’s not really active unless you configure it. Rewards is there as a way for them to make money without having to make Google or Bing the default search engine as other browsers do.
Brave is a great browser, but Firefox is also great and very configurable. And thanks to this thread I learned that FF’s interface can be customized, which was one of my main reasons not to use it anymore. I’ll play with it again, it’s important to have a non-chromium based browser as an alternative.
And that is the problem for the commercial platforms. They don’t want you to leave, they don’t want you to “be done”, they want you reading and engaging as much as they can because that’s part of what they sell to advertisers.
