Oh @vco1 … you have been banging this same drum since you said over a year ago that you were unsubscribing from MPU. Yet here you remain.
Jeebus Crispy… how much more clear could David have been? In THAT URL THAT YOU LINKED TO David explicitly said:
When the Fantastical developers were getting ready to release version three of the application, they asked me to prepare an extensive screencast series on how the app works and how I use it
He also did videos for Fantastical version 2. He has also said that he was a user of the app since long before they hired him to work on the videos.
If you think that means that he secretly dislikes the app but won’t say it because they paid him, then I would definitely stop listening to the podcast.
You should be able to re-install from your “Purchased” list.
Calendar Sets can not only be enabled / disabled via keyboard shortcut, but can also be enabled / disabled based on location. It’s very handy. I normally only want to see my own calendars, but I can switch to “my calendars + my family’s calendars” with a keystroke.
It’s one of those things that seems like a little thing, but if you use it a lot, it’s much better.
FYI - Setapp already includes BusyCal.
