Again I will keep correcting idealistic theories that have no place in Dhamma. The difference between real-life experience and theories is clear here.
“as long as you have not renounced the lay life, you are not in a good position to criticize them” – This is a bad take, is the same idea in clergy and churches, you criticize people or whoever you want no matter their position and status (ask questions, doubt, criticize and seek holes to make Dhamma and people better as long as you do not do it with bad/wrong intentions or harmful ways). If you say that people can not do it, we will have the same thing that in church when priests can do anything and people can say nothing about it.
“If one is really serious about attaining Nibbāna as quickly as possible one should take the robe immediately” – Another delusion is that people who have the first strong spike of positive experiences can not suddenly change their life, get the robe, and become monks – they will become depressed once that first positive experience vanishes and they start chasing it again without realizing the reason behind it (which can be done while being lay), so suggesting people that they should give up everything and leave everything behind to pursue is delusional and idealistic which will harm a person in the process which will harm their practice. For most modern people the best option is to have a comfortable place to practice and study Dhamma, work that can sustain the means for it and without overloading. There was a good book about “free time”, I forgot the name of it but “free time” in ancient and medieval times was a luxury for only those with the highest social standing, every other person worked early to night without much breaks or time – every day that why you became a monk, to have time to practice Dhamma. Now people can manage time on their own.
The rest I will not comment on simply as it’s clear to me that you are “Pro-Dhamma” but not knowledgable or experienced in life/practice/Dhamma to become a person who can say something about it besides slogans. I do not mean it in a bad way, it will be a good example for yourself and others to reflect if one is just “pro-Dhamma” or one following the Path of understanding, experience, and rationale of Dhamma in their life.
Downplaying people on forums “you are just people writing on an internet forum” is really bad too. Lal is just a “person writing a blog on the internet” but the impact he had with the site is huge and brings light to real Dhamma for many people. I strongly suggest self-reflection before writing those things and see if there is any basis in those “arguments”
