Easy way to make sure there are no company names that differ only in case?

But that leaves open the door for "FOO[space]BAR" (one space) and "FOO[space][space]BAR" (two spaces) to be registered, so that doesn't really accomplish the goal of "company names must be unique." If case-insensitivity were really their goal, that could easily be accomplished by choosing a case-insensitive collation for their DB.

Maybe to avoid ambiguity between I and l?

Ah, I see your confusion.

It's "I", me", or "myself" depending on context. The rules can be confusing, but in most context are not ambiguous.
