It's working OK for me, including fleet table, links etc EXCEPT if I am on a ship page in the "management detail" section and click either the IMO company number on the left or on a "details" arrow on the right, I get the "forbidden" page.
HOWEVER, if, on a ship page, I put the company name in the top right search box (for me it has orange letters), the company info comes up, including the fleet tab and list. I get the same results from searching for the company at the opening search page. So it does appear to be some form of glitch (navigation from a fleet list back to an individual ship works properly for me via the IMO number on the left or the "details" arrow)
There is no question of Equasis moving to a commercial basis. The only info they take from MarineTraffic is the very generalised "Geographical information", which MT provide in exchange for the link to their ship photo gallery, VesselTracker. This was, I think, only recently developed and there would also be no question of Equasis paying for it. So don't worry on that score.
