It's been over two years since May Deal was first revealed to the public. I'll believe that the deal is in sight when that's claimed by anyone but british govt/media
The deal that May was negotiating was the withdrawal agreement. That was completed, then slightly revised back to an earlier version when Johnson took over, signed, and is in effect.
The current set of negotiations are a separate set of negotiations, not a continuation of the process started under May's leadership.
Does anyone really care that much about sodding fish? Its economic impact is minimal for both sides.
Either fish has become too emotional a political issue for the UK government to easily let go of or (and I think this alternative is more likely) the UK government tried to artificially inflate the perceived importance of fishing to try to make it seem like a bigger bargaining chip than it really is so that the EU would give them more for eventually conceding on the issue, and now the UK government is getting annoyed that the EU, rather than offering big concessions over fish, is actively trying to solve the issue of fishing rights.
Jesus this is infuriating. Even when it is your own business, these morons couldn't be arsed to do 5 mins of research. Just sitting and ruminating on it for a few minutes would have been enough to realise that Brexit is Godzilla-level stupid. A quick couple of googles can easily dispel the Brexiteer spells.
With fishing, the difficulty is that there is a ton of information out there, and not all of it is easy to parse, and there's plenty of people and publications parsing it in disingenuous and/or oversimplified ways.
Someone involved in fishing as a livelihood could very easily be looking at a small-picture snapshot of the industry where they feel limited by EU CFP catch quotas and perceive fishing vessels from other EU countries fishing close to their home ports as unwelcome competition (and likely heard stories about those vessels
not adhering to catch quotas). Their perception of leaving the EU would be that their quotas go up, other EU countries don't get to fish in UK waters, and they'd continue being able to sell their own (increased) catch into the EU because there'd be a quick and easy trade deal.
In 2016 there were indeed plenty of sites that could be found on Google dispelling those myths. There were, however, plenty of alternative sites that would also have shown up, actively promoting those myths, some of which would have been difficult to disprove for anyone with just a cursory knowledge of the EU (which was ~99.5% of people in the UK in 2016).
In the case of this guy, yes, he clearly did no research, but even if he had, there's no guarantee that he wouldn't have just found some nonsense Brexit-supporting corner of the internet that assured him that the EU was wrecking his life and that voting to Leave would be the best thing he'd ever done. Sadly, what was necessary was not a bit of research in 2016, it was a societal effort to remove EU myths from the UK's national discourse starting at least a decade previously, and that never happened.
