JetBrains here. For clarity, non-commercial doesn't just simply mean individuals. It's a special type of free license for non-commercial use: education, hobbies, etc.

We are communicating this change via a blog post, emails to users, and in-product. With the 25.2.4 update (in two weeks, October 14), non-commercial users will receive a notification about this change and will be able to review new agreement and take action before any data collection happens. For the rest of the users, nothing is really changing unless they are willing to contribute.

No, it's not. This change doesn't affect any of paying customers. Non-commercial is a special type of license provided for free for non-commercial projects (education, hobby programming, etc.), for a limited set of JetBrains products.
