I endorse your viewpoints.

It's what it seems to be in some cases. Even I could say such.

But...
There is more to that.

But the truth is that no one can pull money out of your pocket until you see the value you ought to pay for.

More or less, it pains when you pay for something and simultaneously failed to use it or implement it.

So... A good number of people don't take free stuff seriously.

A price attached would urge you to implement what you learned because you can't sit and watch your money go down the drain.
