I'm not sure how to even reply to the above, honestly I'm confused by what you said so I'll just reply to what I interpreted.

I think they'd feel more frustrated than shame.
As it highlights lack of testing opportunities available from vbulletin.

Why would vBulletin allow them to test modifications and receive support when they didn't pay? If they did this then soon enough no more vBulletin, a company is out to make money unless its a charity plain and simple. If your paid staff spends most of the day providing support to those who didn't pay for it then those who did wouldn't receive the support they paid for. No company will allow their employees to sit around and basically do work for someone when nothing is gained. If a company similar to vBulletin does this please share the link to their website for review.

People who do such, rarely feel shame hence the fact they stole in the first place. Setting up demos, adding email addresses to "free owners" to allow access, all of the above takes additional changes and time - Time is money when it comes to a business.

Judging people who use nulled vbulletin products negatively does not make them childish. Hence I don't really see the need for you to use that analogy/way of expressing what they're doing

Only children who are too young to realize would intentionally steal, if you're an adult the courts tend to label you a criminal and prosecute as such because you should know better - it's expected of you to know better after all its the law.

Those who have/ are using nulled vbulletin product have to be more cautious than those who don't. Most likely from their webhost if nobody else.

Or simply not steal, then no stress in the least and no need for caution. I truly don't know why any company would intentionally allow this, it makes no sense in a business model and as I stated above it would be a lack of income for the company. If the nulled owners unite and start a kickstarter campaign then perhaps but then again the reason why they use nulled software to begin with is the fact they could not afford it so they decided to justify why they could illegally use it instead. I don't see how you justify this to yourself either or push for such a change it makes no sense considering the fact a demo is available and there are countless sites running the mods from here and other third-party script providers that you could simply register and test out well enough to know if you wanted the mod or not.

Different strokes for different folks I suppose.
