I pay for tools independently if they are affordable and I can use them commercially (even at work, even if my employer does not pay for it). I pay for JetBrains yearly and am at the lowest renew cost as a result, so theres no incentive for me to stop paying them yearly. I also saw that you can get Visual Studio Pro for $45 a month, which is really decent considering you get a professional grade IDE all to yourself.
The other thing is they have to be tools I want to use. I am an outlier I am sure. I hear often "let your employer pay for it" but they don't always necessarily pay for the tools I need to use. Having my own JetBrains license grants me strong freedom.
