There's a severe problem I've noted with the answers to How can a company implement a "20% time" program like Google's?
Most of the answers, especially the highly upvoted ones, basically amount to "A poorly managed company couldn't handle this because of X", where X is totally irrelevant to 20% time as Google has implemented it. These answers are basically based on the premise that management is too dysfunctional for 20% time to even exist effectively and they assume truly bizarre time-tracking TPS nonsense that would, theoretically, ruin this idea.
To convert this problem to another domain, this is sort of like asking "in RSA, how can I compute φ(n) if I have p and q" and getting answers to the effect of "I dunno lol that's a lot of math"
The question wasn't asking "How can I incompetently implement 20% time". It was asking how it could do it effectively. Why are all the answers useless discouragement? I find it very concerning if this site is unable to answer questions about unconventional management styles.
When is "no, you can't do that" an acceptable answer? I really don't feel that applies to this question, and it basically creates an environment where any unconventional management topic is going to get answers like "No, my manager wouldn't do that..." which are useless noise.
