I do believe that 1) you would have to back up your opinion that the files were translated by sceptics, 2) give an example or two of bias, 3) explain why the McCanns did not release the professional equivalent and/or point out significant discrepancies, 4) why Kate made no comment about this in her book 5) why the McCanns did not take the webmaster to court and 6) why we can see the originals for ourselves and pick up errors.
As far as I can see, the errors do not show bias. They show a bunch of amateur translators working their socks off and making a rare mistake.
You ask, "3) explain why the McCanns did not release the professional equivalent and/or point out significant discrepancies"
The McCanns paid to have the files translated as part of their endeavour to continue the search for their daughter ... the little girl whose archived case was being studiously ignored by British law enforcement and more particularly by Portuguese law enforcement.

"Every piece of information (in the dossier of potential new leads) was treated the same way - Ricardo Paiva writes on it 'this is not relevant to the investigation',” Mrs Duarte said from her office in the Portuguese capital on Thursday.
“He believed and to this day still believes that Madeleine is dead. I asked him: ‘How can you find a person when you are not looking for them?’”.
She said some of the leads seemed credible, including a cluster of sightings by independent eye witnesses in northern Italy, and had been forwarded by police forces in the UK, Spain, France and Italy but ignored by their Portuguese counterparts.
Copies of the files would now be passed to the McCanns to be followed up by private investigators hired to search for their daughter.
"But I am angry because it is the Portuguese investigative police who should be doing this job,” Mrs Duarte, added.
"They have the power and capability to do it. It is they who should be doing it not and not my clients."
http://www.telegraph.co.uk/news/newstopics/madeleinemccann/7215353/Portuguese-police-ignored-Madeleine-McCann-leads.htmlMadeleine McCann's case is now active ... it is unheard of for the files in an active police investigation to be released into the public domain ... as far as the Brits are concerned, until it is discovered what happened to Madeleine her case remains open.
It should not be forgotten that until her parents managed to have her case reopened Madeleine had been written off because without a shred of supporting evidence she was believed dead by those who should have been looking for her.
For example, Ricardo Paiva and his infamous "not relevant to the investigation" file.
