If you want evidence, look at these two articles from McGeehan in The Guardian, just a few months apart. At this point (2010) he wasn't working for Human Rights Watch so why is he even being given space, not once but twice?
Here's the first in May 2010
https://www.theguardian.com/commentisfree/2010/may/18/sex-and-the-city-2-abu-dhabi
Note that there's no mention of City or sportswashing in this, just a tirade against Abu Dhabi (where he was living at the time). Note also some of the wording:
In contrast to the image it attempts to project globally, the UAE is a country where human rights are systematically violated and where women are routinely discriminated against
This is yet another example of the Janus-faced character of the UAE's rulers. To the outside world they want to portray themselves as progressive (and in Dubai's case their survival depends on that), but internally, their legitimacy to rule still hinges on tribal loyalty and they cannot be seen to abandon what they characterise as Islamic principles.
The country's rulers believe flashy public relations will always prevail over wishy-washy notions of equality, justice and fundamental rights, and that it is possible to go on violating those rights in the most obscene and flagrant manner, as long as the brand remains untarnished.
Now here's another from him, in December 2010, after Qatar had been controversially awarded the World Cup:

Good start
Criticism of Qatar's victory is not just correct, it is highly necessary.
You assume he's going to lay into the Qatari's record on human rights as intrinsically there's little significant difference between the two countries. Both are relatively liberal in terms of religious freedom, broadly following Islamic principles, both absolute monarchies with a limited nod to democracy, both wealthy states keen to project a certain image, etc. Yet his tone couldn't be more different.
While concerns over women's rights and attitudes to homosexuality are entirely valid, there has been no meaningful criticism of what is by far the most problematic aspect of Qatar 2022: the systematic exploitation of the country's migrant workforce
"Entirely valid". That's it. Nothing on Qatari human rights, just the treatment of migrant workers.
Qatar is far from backward: Doha-based al-Jazeera's boldness in criticising its neighbours is testament to that
So Al-Jazeera is "bold" for criticising its neighbours but it probably doesn't criticise Qatar, where it's based. That's more of a test of editorial independence I would have said, yet not a mention of that. And Qatar, according to McGeehan is "far from backward".
The contrast could barely be more stark.
