It would be great if there would be a free tier for people that want to learn C++ with VS. Something that lets you use VS online for small C++ programs (similar with Compiler Explorer but with support for running the generated binary) to build and run these small programs.
No, it would not be great. We should not condone luring people into reliance on closed proprietary technology with "free tiers". It would be great if people organized and got Intellectual Property thoroughly de-legitimized.
The Chinese economy doesn't have intellectual property restrictions to speak of, would you prefer that economy? (everything is a copy of a copy of a copy and most of it is terrible)
How do specialist tools get created, things of high value which take a lot of work to produce and have only a small number of users?
We use money and restrictions on property to allocate resources, if you take that away there is still allocation, but is it always better? (say, squabbling wikipedia or stackoverflow zealots)
