I'm going out on a limb here.
First, the excuse "it's an open source project" seems a little lame. Most open source projects lack good documentation because developer's either can't, or don't like to write. This tool is an excellent compiler and cross-development tool, but there is a lot of old information that needs to be removed and is no longer applicable to current or recent, prior versions.
I think that's fair. Over-reliance on wikis is a particular problem, because (a) the person who wrote an article might not in fact know what he's talking about and (b) there's no mechanism that ensures that information gets reviewed on a regular basis and older stuff at the very least marked as being problematic.
There's also the complementary problem that the FPC documentation conspicuously omits notes of when RTL functions etc. were introduced into the language.
Successful open source projects have well written documentation, and keep it updated. Some users are interested in using the tool, not writing it. Try buying a Jeep kit, yes an unassembled Jeep. They were crated and sold until the 1970's when they were all sold out. Would you rather drive or build your car.
By that metric there are very few successful open source projects, or at least very few that are maintainable by anybody other than the original authors.
I'd suggest that comparison of just about anything with one of the classic jeeps is unfair, since design, documentation and production were underwritten by government resources.
I'm not into listening to you BS, an American English acronym, after 45 years of development so you're barking up the wrong tree boys.
Reminding people of just how well qualified you are (and, hypothetically, that you're a count and KCMG) is never a profitable way to argue. If you're so good then find a way of being useful, or at least pleasant.
I did download the TV manual. The current example crashes compiled with FPC 3.2.0 and Lazarus 2.10 due to a memory management problem. No, I'm not fixing it!!
In that case kindly raise a bug report for it, or at least tell us here in adequate detail what the problem is so that somebody who understands the innards can look at it.
To summarise, you make what are IMHO some good points. But I suggest that a bit more of the "H" is in order.
