It is very easy to criticize, but those who criticize forget the old saying, when you point one finger at others, your remaining fingers point back at you. There are many people who may be jealous/want to take over a large website network, so they criticize the website network owner for whatever he or she does. Since they know they will never be able to develop or manage such a large website network themselves so they become jealous and try to pull down the website owner. Most of these critics do not have a single website of their own and do not have the skills or knowledge for the same or even willingness to spend the money online.
Criticism becomes relevant only when the critic has similar experience or knowledge. When a mediocre inexperienced person with very little indepth knowledge thinks he is “the expert” and passes judgement , it is best ignored. As they say, when a elephant walks, dogs bark.
