Yes, but not neccesary other Chromium do it, that depends only on the corresponding devs. Chrome is a RAM and Data Hog, because use for every tab a own process, but Vivaldi Hibernate the background tabs and because of this use less RAM than other Chromium and even FF. But generally all US browsers send data to Alphabet, googleanalytics and googletagmanager, except Edge (also Chromium), but in change it sends data to other MS partners which are even worst (Towerdata). I use Vivaldi for this, because it's the only existing EU browser (after the French UR browser died some years ago) maybe apart Konqueror from KDE (Linux only, KHTML or KDE WEBKit engine), no data for third parties, nor Google, despite the Chromium base. The Browser companies are the problem, not the engine which they use.
