Here is the Twitter thread in that article.

Then, there's this "article" in Briefings-for-Brexit, which reads like a hard Brexit blog.
https://briefingsforbrexit.com/prime-minister-misleading-country-on-security/ His arguments are certainly not how I read pp 17 et seq of the political agreement. I can't see any abrogation of sovereignty anywhere in it.
My impression is that they just that they wanted to vote down May's deal. The sceptic in me makes me wonder if there are US interests in the background.
From the last section of the Wiki page on Dearlove,
"On 8 June 2017, Dearlove intervened on the day of the 2017 UK general election in The Daily Telegraph saying "how profoundly dangerous it would be for the nation if Jeremy Corbyn becomes Prime Minister."[24]
On 29 November 2018 Dearlove co-signed an open letter, published in a British national newspaper, condemning Prime Minister Theresa May's negotiated Withdrawal Agreement for the United Kingdom from the European Union after the 2016 Referendum on the issue, as the matter was passing through the House of Commons to be voted upon. In its text he stated that the Withdrawal Agreement as negotiated undermined MI6's nationally independent global intelligence power.[25]
In a published response, dated the same day, the Prime Minister's Office issued a public "rebuttal" to the letter's content, singling out Dearlove personally from the named list of several signatories to the open letter, stating the Withdrawal Agreement "absolutely does not" compromise the national independence of the United Kingdom's Secret Intelligence Service's capacity.[26]
In early December 2018 Dearlove, in a jointly authored text with Major-General Julian Thompson, published on the website 'Briefings for Brexit' an extensive reply to the Prime Minister's Office's statement entitled 'The Prime Minister is misleading the country on defence and security', citing a 'worryingly poor understanding of the issues' by the Prime Minister's office.[27]
On 8 January 2019, in an extraordinary intervention in the political sphere by figures from the S.I.S. and the military quarter, Dearlove sent a letter, co-signed by Field Marshal Lord Guthrie, to all Chairs of Conservative Party Parliamentary Constituency Associations with sitting Members of Parliament stating that the passage through the House of Commons of Prime Minister Theresa May's European Union Withdrawal Agreement contained decisions which fundamentally undermined the integrity of the Defence of the Realm, and requested that they take measures to discourage their parliamentary representatives from voting for it imminently in the Commons.
The letter as an alternative advocated the case upon national security grounds that the United Kingdom should fully withdraw from the European Union without an Intergovernmental relationship between the two persisting after the process.[28][29]"
