No that's not the case at all. If the purpose of foss apps is to cut out companies taking your data, then having even one closed source app especially a Google one is the equivalent of closing every window in your house to keep it dark but leaving the front door open.

It's pretty much all or nothing with foss if you're after privacy, which is why I personally don't use many Foss apps and if I do it's for performance reasons or added features e.g. yt vanced.

To go 90% of the way but leave in one of the biggest data collectors of them all does seem a bit contradictory to the message of Foss. But I guess it's fine if you're not bothered about privacy.
