The article is full of concrete reasons not to buy an M1 if you use Microsoft and Adobe software.
I suspect the number of Edge users in the Mac ecosystem is not high. Acrobat might be more of a problem, but it's still not quite the mainstream MacBook Air use case.
The question isn't so much "Do these apps work?" but "When will they work?" MS and Adobe will be distributing Apple Silicon builds within the year - most likely within six months, and possibly by early next year.
So these are showstopper problems if you need these applications on a Mac right now, but not so much if you're planning to wait and see a while.
Honestly, Catalina and Big Sur broke far more applications than the M1 move did. If you're doing the prudent thing and running a year or so behind it's very likely there will be fewer problems.
So ultimately there aren't many reasons beyond novelty and a percentage of natural replacement why most people who lean heavily on Office and Acrobat are going to need a Macbook Air right now.
