I believe GP is referring to the EU 'forcing' the UK to put a border between Britain and Northern Ireland, because the EU wanted a hard border somewhere and wouldn't budge on that.
The EU have offered many opportunities for the UK to harmonise with the EU on many issues, while continuing with Brexit. For the most part, UK rejected repeated offers that would grant UK people and businesses more rights.
For example, the rights of British people to freely travel in EU countries could have been kept, but the UK said we don't want our people to have that, as the price of mirroring it by allowing EU citizens the ability to travel in the UK is too high.
EU offered to let students from the UK travel through EU under the Erasmus scheme. UK said no.
EU offered a customs union, where standards were more harmonised and the would need to be far fewer checks at borders. That would have been far cheaper for every business in the UK that sells into the EU. UK rejected that. UK actively wants to diverge from EU standards (e.g. for things like food). It shouldn't be surprising that EU will protect businesses that conform to those standards over those seeking to undermine them.
Businesses in Northern Ireland currently have advantageous access to the EU in ways no other part of the UK does. I don't mean the physical access to Ireland, I mean administrative access to the EU markets. You can see it in tax and import/export forms. There are currently reasons to set up businesses in Northern Irelend to get that foot-in-both-worlds advantage.
A lot of businesses in the UK mainland would love to have the same rights as businesses in Northern Ireland. Especially those in Scotland who didn't vote to leave anyway, and see it as an England-imposed harm on them.
What would you expect should happen, that UK should be allowed to use Nothern Ireland as backdoor to send unchecked goods to the EU, imported from say the USA and Australia and re-exported into the whole EU market with no border checks anywhere?
