It does look (now), based on this arrest, like the Turkish Grey Wolves may have orchestrated these two bombs in response to the forced deportation of the Uighurs.
Not sure why the authorities are obfuscating the reason - OK I understand, but it makes them look even sillier to pawn it off as "personal", rather than just acknowledge it as political, and then even re-spin it as positive for having forcibly deported those Uighur "terrorists". But they may want to avoid further incidents so will "walk the middle path"?
A few articles from before the arrest.
Bangkok bombing: new theories turn to Turkish travellers, Grey Wolves
Anthony Davis, a veteran security analyst with IHS-Jane's, has suggested that the most likely perpetrators were ultra-nationalist members of a far-right Turkish militant group called the Grey Wolves.
Speaking on a panel at the Foreign Correspondent's Club of Thailand on Tuesday, Mr Davis said the Grey Wolves, an extremely violent group, and the unofficial youth wing of Turkey's Nationalist Movement Party [MHP], took part in attacks on the Thai embassy in Istanbul in response to the Thai military government deporting Uighurs to China in July.

Thailand's Shrine Bombing - The Case For Turkey's Grey Wolves
The most likely perpetrators of the deadly Bangkok bombing last week were militant members of a right-wing Turkish organization infuriated by the Thai government’s forcible repatriation of Uighur refugees back to China. Anthony Davis, a veteran security analyst with IHS-Jane’s, made a persuasive case for the Grey Wolves on a panel at the Foreign Correspondents Club of Thailand Monday evening.
He did not rule out the possibility that other foreign militant Muslim organizations could be responsible for August 18 bomb at the Erawan Shrine that killed 20 people and injured 126. He found it extremely unlikely, however, that it was the work of Thai dissident political groups or even of the Muslim insurgents in southern Thailand who have waged a separatist war in three border provinces for the past decade.
