Attitudes like these is why non-developers don't want to use open source software.
These concerns may not matter to you, the developer, but they absolutely matter to end-users.
If your prospective user can't find the setup.exe they just downloaded, they won't be able to use your software. If your conversion and onboarding sucks, they'll get confused and try the commercial offering instead. If you don't gather analytics and A/B test, you won't even know this is happening. If you're not the first result on Google, they'll try the commercial app first.
Users want apps that work consistently on all their devices and look the same on both desktop and mobile, keep their data when they spill coffee on the laptop, and let them share content on Slack with people who don't have the app installed. Open source doesn't have good answers to these problems, so let's not shoot ourselves in the foot even further.
If my user cannot install software in their own computer then I do not want their money. They have issues they need to work out on their own and they might be better off saving their money.

Good! It's not for them! They can stay paypigs on subscription because they can't git gud!
I'm a seasoned developer and I frequently come across OSS projects where I spend half an hour or more in "how the fuck do I actually use this"-land. A lot of developers need to take the mindset of writing the documentation for their non-tech grandma from the ground up.
This presupposes that the OSS creator even wants users in the first place, which might not always be the case as it could be personal software; and that these users actually want these features, as many do not want analytics, ads, and A/B tests in your app.
