Also, in big corporations, getting approval for spending $20 is as hard as getting approval for $200 or $2000.

Which is why FOSS software took off in big companies, because it's easier for developers to sample things out and then ask for forgiveness instead of asking for permission.

Also, hobbies. It doesn't even matter if you have $20 to spend, or not. Hobbies depending on paid tools are risky.

People underestimate the importance of free tools because they judge from the perspective of their overinflated consultancy rates.

Then again, this sort of decisionmaking is probably why you're a software developer with less than $20 in your bank account.

I don't know... Possibly because your life circumstances made it that?

But hey! Talented people doing their best to break out of poverty is clearly a novel idea to you.
