I suspect it’s a site made by disenchanted Lubavitchers who are now probably MO, and it is not a site that represents mainstream Litvish opinion.
It’s hard to trust a web site that doesn’t identify its author(s) or provide any contacts except for a gmail dot com address. The whois data for the domain gives the name and address of a person in Lakewood, NJ, but that’s not necessarily the site’s author.
