Rather than trying to solve your problem by preventing other plugins
from loading, you should instead solve it by finding the correct
method to do what it is you want to do. In other words, you should
treat the cause of your problem, not the symptoms.

Your main issue is that you're manually including wp-load.php, which
you should avoid. There are better methods. Otto has a good blog post
on the subject [1]. One thing that Otto didn't touch on is using
admin-ajax.php too, for loading resources or fulfilling requests. This
is worth looking in to.

Secondly, your post is a prime example of the XY problem [2]. You're
concentrating on your attempted solution rather than asking advice
about your actual problem. It might be worth starting another thread
detailing your actual problem, then hopefully someone can help out!
