IMO when Olympus lost their identity of being different, they lost their mojo.
Back in the film era, the OM series were the smallest and lightest SLRs you could buy and the Zuiko lenses were first class quality. Others tried to build lighter cameras with more plastic, but none could match the OM for both size, weight, and quality.
In the consumer market, they also had great point and shoot cameras like the clamshell XA and XA2. Those are still hot items for the retro crowd.
The only Olympus digital I owned was the E-10 back in 2000. Awesome lens, but a camera with serious power and speed issues that rendered it useless. As I prefer an OVF, I never returned to an Oly for consideration as a system.
The only Olympus product that has stood out from the crowd was the Tough TG waterproof series. But even with the 2019 release of the TG-6, to have a 12MP sensor?
I did meet a Magnum photographer around 2010, Eli Reed, who was an Olympus Visionary, a support organization similar to the Canon Explorers of Light or Nikon Ambassador programs. He shot and was supported with all Olympus cameras. Currently I believe there are only three Ricoh Imaging Ambassadors and I wish they were more visible to enthusiasts and pros:
