MS Office doesn't need permanent approval. I have Excel, Word, Powerpoint, Autoupdate and Update Assistant blocked from making any outgoing connection (on MacOS). That works for about a month, then I have to unblock briefly to let the licence check work. I don't use Adobe these days.
I got rid of both, not too long ago, but even trying to be careful about approving office chatter got me that read-only license check bar all the time. And getting rid of it meant clearing rules and blanket Approve for a time, or a flood of individual ones.
Also excising Adobe was not simple.
