This justification is even worse than the domain squatting itself.
Some of the most influential software in history (Linux, Git, GCC, and yes, PuTTY) thrived under community-driven development. The idea that software "dies" without a single corporate owner is not just false, it’s insulting to the open-source ecosystem.
If Bitvise truly believes in their philosophy, they wouldn’t need to borrow PuTTY’s reputation by holding putty.org. Maybe they should spend less time on branding and more time studying how successful open-source projects actually work.
