Smaller group and often less willing to put out cash for it (besides the few who would be willing to pay substantially more to get great applications on Linux).

This was the belief for a while, but it seems that isn't totally true.

"Pricing wise, we haven’t noticed anything that distinguishes Linux users from everyone else. They are no more cost conscious than Mac / Windows users. They are definitely willing to pay for software."

As an on-again/off-again linux user, I have paid for software or donated to many projects and it seems others are willing to do the same, however it is still a much much smaller group.

I know many developers working on Linux laptops (web backends.) I do since 2009. Would I develop some GUI tool with the aim to sell it? No chance. Gnome or KDE, apt, yum, flatpack, snap, etc? No thank you. I take what's available and that's it. Ubuntu has proven for 11 years that's more than enough to give me a desktop I like (currently a heavily customized Gnome Shell) and pay my bills.
