Responding to "it's cruel" with "they're allowed to do it" is kind of sidestepping the core of the complaint.
I highly recommend that you refrain from commenting on any immigration related topics until you can get your facts correct.

You say:

when in fact the visa very specifically allows it (as per the "no intention of abandoning"). People arriving in the US on an H1B visa with immigrant intent are absolutely following the law. Is it a good idea? Much more debatable. But they're not acting without precedent nor without specific legal text allowing it.

No, there's nothing proper about it and it has nothing to do with the merits of the visas in question. There is no law saying that the state department should make travel impractical for people USCIS has already decided can live/work in the US. The reverse is much more likely. They want to push people off of legally obtained visas by causing unreasonable delays.
H1B is temporary but you can have immigrant intent. It can be extended indefinitely with an approved green card application. Your employer is going to pursue that if you're on h1b and they want to keep you around. Many if not most h1b holders are in that category and will get a green card eventually. They are simply waiting for that to be available due to quotas based on their qualifications and birthplace.
