@freemo yet again, building walled garden with a transparent wall is a formal, rather than functional difference, regardless of enforcement.
I am reserving all judgement as to whether "your" or "their" walled garden is "better", so your arguments as to why it may be so aren't particularly relevant to this specific thread.
My sole contention is that, based on personal observation, your proposal attracts a degree of ridicule and pushback by virtue of appearing to claim to "solve" the problem of walled gardens by implementing the problem differently. My recommendation is as simple as it is impossible; relinquish the oppositional mindset. Let "them" talk however they will of you. The difference of experience within your garden will be the only rebuttal of theirs you ever need to make.
