I find this argument quite bad. It was done in the past and it's still being done today. There's nothing preventing any company from doing it except for a combination of laziness and greed.
This was also the excuse people gave for GDPR and California's privacy law and everybody got forced into complying after the date of validity. Simply having an "excuse" of money loss due to engineering your game user-hostile in the first place (especially after the law became valid) isn't a good argument. It will have some preparation time and if you didn't plan for it, it is your fault.
And yet releasing standalone servers back in the 00s was the norm, rather than the exception. I don't buy the argument.
