It is rather strange mate isn't it. You can only assume that some lack the intelligence to use critical thinking and given only one side has really voiced their side that they have lapped it up as the truth. No doubt Wilder made mistakes on AND off the field and did himself no favours with some of his media interviews, however by all accounts he may have been in the midst of a breakdown of some sorts. There seems to be a narrative that Wilder realised he was out of his depth; that his signings were failing, his tactics found out, and he had lost the players, and thus tried to get out to avoid a relegation on his CV, which of course could be true.
The other possible side is that the Prince had decided that he wanted to fundamentally change the structure at the club; that Wilder was being vetoed on his signings, that he was being told who to sign, and possibly being told that he needed to keep playing some players so they retained their value. It could just be that Wilder felt that as mentioned in this thread, he had taken the club as far as he could (either in his capabilities personally or in his perceived hands being tied) and wanted to resign due to a fundamental rift in his and the Prince's philosophical ideals. Who knows, but it is sad that some are taking the Prince's version as gospel. The truth as they say is probably between both options. The sad thing is that over time it seems the Wilder critics are getting more and more vehement, time does not seem to be a healer in this situation. If you sell both Berge and Ramsdale for say 60 Million they certainly won't be updating their opinions and will still likely stick to the 'Wilder spunked 120 million up the wall' lines. Time will tell on Brewster and McBurnie, so far they don't look too great, but if they improve like Ramsdale has it will be all SJ's doing. I don't think I have ever seen such a hero to zero so quickly, it is very sad.
