I think this is the reason why bigger guys go for weights, whereas smaller, shorter guys go for calisthenics. Bigger guys move more weight from the get go, which motivates them. Smaller guys starting out can do like 50 pushups in a row and that motivates them.
The amount of hate on weightlifting in the Convict Conditioning series is like reading a diary of a chubby girl's impotent rage on why she will never be pretty or get attention like her more popular friends (lol).
I agree wholeheartedly with H1N1 here, calisthenics definitely have their place in a training program. They encourage mobility and higher levels of relative strength, which also discourages high levels of bodyfat.
The way I looked at it, even though the shorter gymnasts were going to get full planches and maybe even feats like the manna or the maltese with enough time and dedication, I could get a lot of mileage out of simple stuff like pseudoplanche pushups and different variations of bodyweight rows.
Foundation 1 was great and I made some good gains with it, but one of the things I really didn't care for what the need for strange or improvised equipment for certain mobility exercises. It seemed to defeat the purpose of a program where the draw was that you didn't need a set of weights.
"Street workout" has gotten popular in certain places of the world because there are no gyms or the people doing them are too poor to afford a membership.
It's better than nothing and the results (with enough effort) speak for themselves. If you live by a playground and you don't think you'll get arrested, you can go there instead of the gym and just hammer on pullups, dips, and pushups for an hour a day.
