Ladybird is fairly new. Just like how Mozilla didn’t get Gecko to this point in 1 year, Ladybird will take years of development to become a reliable browser and browser engine.
I pretty much agree with you. The alternatives are far worse. Seeing Google Chrome and Microsoft Edge being literal spyware, other Chromium-based browsers cutting out support for content-blocking extensions Firefox is vastly superior to them in terms of privacy. Although that still doesn’t mean Firefox is good, at least if we’re past talking about web browser engines etc., using another Firefox-based browser which is less bloated (Firefox Sync off by default, no Pocket, no recommendations in Addons tab), more privacy-friendly (all telemetry off by default, uBlock Origin installed by default, some hardening options from about:config enabled by default) seems to be the best choice currently, since other options like GNOME’s Epiphany and KDE’s Falkon sucks, if we’re being honest.
And I do kind of fit your description, if we exclude being a conspiracy-theorist.
