Fiddler Classic changing their EULA to allow solely non-commercial use.

Better back up your old installer FiddlerSetup.5.0.20253.3311, because starting w/ FiddlerSetup.6.0.20261.7291 && beginning w/ 2026-09-17, Fiddler Classic can be used solely for non-commercial uses. Sucks for me, given I use the software very rarely for some work-related tasks.
