Yes and no, it use affiliate links and search engines (DDG, Startpage, Ecosia...) which pay some money if you use these, but you can delete these without problems if not. Vivaldi use this to create incommings, instead of selling user data and browser logs to third parties as other do. Fingerprints, well, it protects some fingerprints which are an privacy risk, but spoofing all can break some webs. Fingerprint protection is always an balance between what is necessary (eg. tecnical data to show correctly a page, eg your screen resolution) and what is not. Your Public IP is always shown in any browser, if you don't use an VPN (Proton VPN inbuild in Vivaldi) or Proxy, but the public IP only show the one of the server used by your ISP which can be hundreds of km from your real location, but it made that the page is shown in your lenguage (if it has this feature). If a website use Fingerprinting (not often), it use those from the whole device and OS, not only from the browser. Vivaldi never logs your activity or track you, never share your data with third parties, no third party sponsors in Vivaldi. Sync is encrypted end2end, no knowledge (if you loose your encryption password, you loose your sync data!!!). stored in own servers in Iceland (green energy). IMHO Vivaldi is pretty private.
