I actually like when I get the note that I need to pay for the upgrade. It's a good reminder that I still find Sublime valuable (so much that I use almost daily), and that I got 3-4 years of free upgrades for a fair price (vs. subscription models like 1Password, or version-specific rip-offs, like VMware Workstation).

It's one of my favorite piece of software. Obsidian being another one.
