Nope. The controversy continued for some years. They didn't just snap into compliance, they were playing games, who knows if they still are.

It's been a while and I'm not aware of an "official" collection of events, but here's a list of the things I remember:
-) Initially, they created a kickstarter [1]. You can see their claims of open hardware and open software. Initially, they had removed all traces of sigrok/PV from the UI, even though they did retain certain copyright notices and sigrok references in the source. [2]
-) From what I remember, Uwe made them aware of this but it wasn't until mid-2017 until they changed it. [3]
-) Their initial firmware was based on fx2lafw but they removed all copyrights and fx2lafw/sigrok references in their initial commit [4]. Only after Uwe made them aware that this violates the GPL, they added sigrok references and reverted the copyright messages [5].
-) The DSLogic-fw repo on github contains an old firmware that is no longer used. They claim to now supply firmware (in binary form) that is no longer based on fx2lafw, though they never made the source available. We are uncertain whether they truly rewrote the firmware from scratch or whether they simply smartened up and mangled the code. They're not giving us much to work with here, so it's easy to assume the latter.
-) Their git commits almost always consist of a LOT of changes squashed into a single commit. Intention is unclear but I suspect that that's their way of complying with the GPL while preventing anyone from really taking back from the project.
I don't remember whether their kickstarter initially mentioned sigrok or whether they edited the text later on to include it. Either way, it is obvious that their intention never was to give back, only to take and make money off of our work. That's what I'm so sore about.

The January 15, 2014 date I mentioned came straight from the OpenTechLab video you linked to -- at around 30:20, with a Github screenshot showing that date. And Joel mentions that they continued to maintain the repository, and that the Sigrok camp was still divided (6 years ago) whether DSLogic were initially violating the GPL on purpose or whether that was just an oversight on their part.
Anyway, you obviously don't have to buy a DSLogic unit. I might, if I find a reputable European reseller who provides warranty and a return option.
voltsandjolts:
Joel was more trusting and sanguine than other sigrok contributors. The sigrok project seems to have lost most of it's contributors now, I doubt whether anyone is actually checking DSLab compliance these days.
Johannsen:
I was very happy that my question received so many answers..unfortunatly when I read those none actually replied to my answer but to some controversy story.
I just saw that sigrok supports the pre 2023 DSlogic Plus version. They write that on their website and if they would super angry about the hardware they wouldn't support that.. I would guess but it's not the question of this thread.
Nice to hear at least that DSview works well.
I'm still thinking about which hardware to get and with a student discount price the smallest Saleaa is still 3x more expensive than the DSlogic plus and the DSlogic is propably more modern than the Saleae

For those who choose to not use DSView due to considerations surrounding software freedom, there is a famous precedent for such a position: See How I do my Computing by the inimitable Richard Stallman.
