kiruaAlternatives to gmail products (gmail, office, etc)
shapisChrome -> Firefox
Gmail/Calendar/Drive -> Proton
Office -> LaTeX/LibreOffice

You gotta wait for overture maps alternatives. It is an open map project by the linux foundation, microsoft, tomtom and some other companies. Its main purpose is to provide a competent competitor to google maps since these companies don’t want to pay google royalties for their map data. It can also help osm since it is under an open license i think. It is still in alpha though at the time of writing this…
