You are in luck. COSMIC launches in 3 days.
I am also interested to see what kind of adoption COSMIC gets. From the comments I have seen, I looks like it may pull-away a fair number of GNOME users.
No sure that COSMIC calendar will have all the features you want. COSMIC is a pretty good base for GNOME apps though. It does not have to be either / or.

The GNU projects that people actually use are primarily hosted, maintained, and developed by Red Hat (IBM). They are the primary code contributors. Not just GPL, GNU specifically.
This is just a fact.

There is more permissively licensed code in most Linux distributions than there is GPL code. Not only is that permissive code not being “stolen” by “mega corps” but the majority of it is corporately funded.
Again, just facts. All pretty easy to verify if facts matter at all to you.
What part did not make sense? Just that the facts do not agree with your opinion?
The comment I responded to was stating things that sounded like facts that are not at all supported by the evidence. And if I ask for some, I am pretty sure the cherry-picked examples will be mostly companies “stealing” projects that they wrote to begin with.
The thesis that permissive licenses result in less Open Source code is wrong. In fact, they lead to greater corporate participation and employees write more code than unsponsored individuals. That is what the evidence shows.
Use whatever licenses you want. Not wanting companies to use code you wrote is a totally valid choice. But you should not have to misrepresent reality to convince other people to do the same.
