doesn't make much sense
"a de-Googled tablet makes more sense than a de-Googled phone. It's now common, even normal, to do contactless payments with a smartphone, use it to store tickets and membership cards, run banking apps, and so on. A device that can't do this, or even makes it harder, is significantly crippled."

Those of us who belong to the latter group tend not to also inhabit the former.
I am in my seventh year of using e/OS/ on phones and can see no use for a tablet in my life.
