I defer to the IT / Digital Legal Companion, by Gene K. Landy, an actual lawyer:
"The Myth of the Two-Page Contract
... Many times a client has brought us a complex multiyear distribution deal and wanted a 'simple two-page agreement.' Sometimes, they even ask for a one-page deal! The ostensible goal is to cut down negotiation time. But for most negotiated deals, it is a myth that adequate contracts can be short in this way. If the lawyer tries to comply (and we have tried), the result will almost always be to make the deal ambiguous. ... Managing complex deals full of contingencies with as imprecise a tool as the English language is tough enough; it is not prudent to try (or force your lawyer to try) to make agreements more risky than they have to be."
The sentiment could not be more clear: all that legalese is in the agreement for a reason. "Simplifying" licenses into bullet points does not adequately capture their content, and it is a huge UI fail to make people think that it does.
Let's start with the site's treatment of GPLv3. You get a few bullet point labels about e.g. source code disclosure plus a three-sentence summary. "GPL v3 tries to close some loopholes in GPL v2." Oh, really, what are those loopholes? No discussion of code signing, patent rights, affero vs. non-affero, among many other issues.
Even the bullet points themselves do not adequately capture nuance. That the GPLv3 allows commercial use is technically true, hence the label "commercial use". However, what isn't mentioned is the fact that the GPLv3 separately prohibits practically every known business model for profiting from software.
These ambiguities are not minor issues; they are fundamental. Let's not wrongly give people the idea that complex licenses can be summed up with a few bullet points, any more than our technical work can be summed up with a few crappy analogies!
