What features did you lose in Fantastical?
I wouldn't recommend it anymore either because of the subscription model, but I don't see any functionality missing compared to the previous version.
The only drawback for me is that the UI takes more space.
You can't even see the date in the menu bar without paying. Those who don't pay see a menu item that has no date. That was egregious. However, previous versions also had the "travel time" feature that's already an macOS Calendar.app feature.
Finding out that macOS/iOS Calendar is perfectly fine for me.
I really wish Flexibits had created a different app without the cloud features and let this one languish. Clearly they needed a "teams" version for families/small enterprise that they felt they could monetize. That they bundled it into their main app annoys me.
Same with 1password - but in that case, I felt it was worth my subscription (family for several users, admin capabilities worth it alone).
