The other issue he mentions would probably be related, if you were running WP-Script on an under-resourced small hosting account then the max execution time of php may be limited or speed of external bandwidth may be limited, this should easily be fixable by increasing max execution time in php.ini - however if he were on a crappy shared hosting account he may not have the option of editing php.ini.

I'm running WP-Script on small containers without issues. I think you just have to accept the fact that you can't make everyone happy 100% of the time, because no matter how good your script is or how good your support is you will come across people who are never satisfied or not technically competent enough to install and run WP plugins or themes.
