No, I don’t use TOR, it’s not really more anonym in the ordinary web than other browsers, it’s only slower and less secure. Certainly Chromium is made by Google, but as OpenSource, the script can be modified, well as degoogled Chromium or let the user decide which Google APIs need and which not in the settings, as Vivaldi do, because there are also users which need some services for their work. A lot of online services and profesional sites need services que offers Google and which don’t have valid alternatives. Because of this, also Gecko use them, but you have to modify the script to eliminate it, in Vivaldi you can do it in the settings or at least in flags. As you can see, FOSS have advantages for devs, but not so much for a normal user who need certain features for his work, study or activities. Privacy and security has nothing to do if te product is FOSS or not. The normal user need a good tecnical support and devs which respects the need of the user (most features are added by request made by the users in the community of Vivaldi where the devs and even von Tetzchner itself particpate). Nothing to do with the habits of Big Tech and prefab FAQ pages as support, or implement or rest functions, without consens of the users, as FF do… Where are here the advantage of FOSS over a product OpenSource who use 5% auditable and customizable by the user but proprietary code?
