I'm an Oppo owner and just read this awful news as well. If this has been already said, then just ignore this.
Oppo is owned by BBK Electronics. BBK Electronics owns Oppo, Vivo, and One Plus. I own an Oppo 105 and love it. I've been an iPhone user for years but didn't want to sink over $1000 into a phone. I found out Oppo makes cellphones. Oppo makes a cell phone that is all bezeless while the iPhone has a big notch in the screen. It's called the Oppo Find X. It's also $1000 but when you need the selfie camera or Face ID, a motorized camera pops up and detects you and lets you take pictures. However once durability tests were done, the Oppo Find X got horrible scores. Vivo also makes a bezeless phone with a pop up camera but also like the Oppo, nobody really caught on.
The bright spot is BBK's third company, owned by Oppo, call One Plus. So, Oppo makes a fancy phone and then 6 months later a more realistic phone is made by One Plus and is sold under the company called One Plus. One Plus is now a HUGE cell phone producer outside of America. Their current phone, the One Plus 6, is the fastest phone in the world, faster than the newest iPhone and Galaxy or Note. It's also at about half the cost. They are getting really popular and now they have headquarters in Seattle and are looking to partner with carriers to be the next big brand of cell phones in America. They've made 6 models for 6 years and people are still using their six year old phones. I bought a One Plus 6 and I really love it, no, loved it. Then the new Android software came out and then One Plus released their compatible Oxygen OS to go with it. Now my camera is worthless and the display looks terrible. The company tells me to be patient because they are addressing tons of "bugs". In the meantime I have an almost new phone with a terrible camera and screen.
BBK is pouring money into expanding their best product line and now their best product line isn't Oppo, it's One Plus. The Oppo phones have been a flop and the One Plus phones have been a huge success. One Plus is releasing their newest model, the 6T, on October 30 and the internet has been buzzing about this for months. My guess is that BBK saw that One Plus was the future and Oppo phones were killing them, so they decided to move forward with One Plus instead. One Plus is also making other electronics like wireless "air pods" called "bullets". They are wanting to be the next Apple. And their new model coming in a couple weeks has fingerprint unlock built right into the front glass display, along with Face ID of course. They seem to be the leader of innovations on cell phones right now. Their newest model also has the smallest "notch" on the screen because they figured out a way to put the phone speaker on the top edge of the phone and then only needed a tiny notch for a tiny front camera. So, for BBK Electronics, One Plus seems to be the future and that might very well be the reason that Oppo is on the way out. Maybe for all of BBK Electronics's companies, One Plus looked the brightest. Who knows, maybe some day we'll see a really good One Plus Blu Ray Player? They are already making a laptop, not yet available, but it's a MacBook Pro ripoff in my opinion but it runs Windows 10 of course. One Plus seems to be a stupid name for a business, but Oppo wasn't the best name either! So, even though Oppo is done, BBK is doing well and they could, at any time, make any Hi-Fi line in the future. But for now it seems that BBK thinks the future is smartphones and they tried smartphones with Oppo and Vivo and that didn't work out all that well especially compared to One Plus. I'm saying, I don't think it was their Hi-Fi equipment that killed Oppo, I think it was their smartphones.
