> Remote work eliminates a lot of problems with office work: commutes, inefficient use of real estate, and land value distortion. But software development is better when you breathe the same air as the folks you work with.

It's pretty hard to know where the opinion is.

The whole paragraph presents as though author is relating known symptoms of a disease. We're never really sure which they themself actually experienced. They look more like arguments in support of a cause.

Author is totally entitled to open that door, but then it also becomes fair game to attack the perspective.

I am pointing out the fact that he is using factual statements in support of his opinion. "Remote work sucks" is an opinion. "Pair programming is less fruitful" is a statement of fact (regardless of the veracity of the claim).

"It is my opinion 7 x 9 = 63," wouldn't be an opinion in the sense that opinion was being used in the thread. Yes, we can question the veracity of a statement of fact, but that isn't the same sort of opinion as whether something is subjectively good or bad.
