Yes. They need to write installation instructions, and the more complex
those instructions are the fewer prospective users will bother.

The more complexities in the installation process, the more
opportunities there are for the recipient to make a mistake. Each
mistake is demoralising and will cause some proportion of people to give
up.

So if the installation process *necessitates* complex instructions,
that's a problem for the developer.

You can blame “lazy users” if you want to. That gets you no new users of
your program though.
