Literally never. This topic is one of those things that draws resentful ruleboys out of the woodwork to preach about something they have no firsthand knowledge of because none exists.
The fact that these visas are becoming available means that governments are wising up to the fact that people have been working remotely on tourist visas and want in on it. They want to be able to charge for it, or set a limit on who can do it, or tax it.
Now that these visas exist, and immigration officers know that, it’s only obvious that they’ll start to ask ‘tourists’ if they plan on working remotely or not. You can lie all you want, but if they find evidence (two laptops, notebooks, equipment) then good luck.
What happened in the past is just that.
If they disliked the idea they wouldn't be creating new visas for the purpose, since that only makes it more prevalent and normalized.
