Go apply to be a beta tester. So long as there's a reasonable flow of usefulness from you; bug reports, ideas, feedback; you effectively get Maxon One for the entire duration.
I haven't personally paid for c4d for 25 years now 😉
For a quick reference, and extrapolating back a little as the current database doesn't go back the whole 25 years, Im currently sitting on ~1700 bug reports, ~700 testing other people's bugs and 1100 ideas for features/changes. This is roughly one idea or bug every 3 days. Some of this will be small scraps like "The hitbox for this button needs to be extended 2 pixels to the left on 4k screens". And others will be larger scale testing reports where time is spend trying to pinpoint the exact cause of a problem.
Actually on second thoughts money for bugs sounds like a great idea 😄
