Being proficient with ones' tools does not mean you should be unable or unwilling to also admit that they have shortcomings. Better tools means improved productivity and products, try not to be so myopic.As another user says: "It is a poor workman who blames his tools... "
These common criticisms, often posed in a supportive or constructive way are often quickly dismissed by the same people repeatedly. the more you use FreeCAD the more blind you become to certain problems and it is so common to see forum regulars pile-up on posts like these with little regard to the validity of the items being pointed out.
There are less socially toxic ways to encourage people to get involved in the project than the "learn2code", "haha you just don't understand FreeCAD" and "FreeCAD isn't xyzCAD".
Often, people like the OP appreciate the program and what its capable of but experience some frustrating things they encounter as part of the learning process and actually want it to become better than it is today. While not all criticisms that wind up on the forum are valid or well articulated, this one certainly seems to be. Jumping in with overt and covert negativity does absolutely nothing to help build a stronger community. It actually does the opposite.
All of this aside, I think @chrisb really put everything into perspective with his response.
@hauseru thanks for coming to start a conversation from the perspective of a fresh set of eyes. Despite what could easily be taken as a bunch of negativity, please understand that everyone here is very passionate about FreeCAD. Most of the items you've mentioned are well-known and have been 'beaten to death' here on the forums many times over. If you are willing, and capable, a foray into the source code to fix even one of the things you've noticed helps make FreeCAD that one bit better than it was before.
Either way, I think if you stick with it, you'll find that after you better understand the FreeCAD approach you'll find it rewarding and less complicated than you initially thought. Best of luck to you!
