Therefore the question:
Why should one should buy another product from a company that treat some of their user-base so badly?
Why should a company invest in Altium Designer with such a bad history that Altium has with CircuitStudio?
Customers will put up with a lot because they are locked into the tool, either through personal time/skills investment or through their company.
I've lost count of the number of times Altium have peeved off customers big time over at least the last 20 years, the list is long and distinguished, it's not a new thing, yet they never lose customer base.
Sure the odd person here or there takes their bat and ball and goes home, but most do not, they just stick it out and grumble about it and play the long game.
