you missed the start of that same phrase, the additional investments were made to support global expansion. Not to fill holes.
I do understand your concerns to invest in resources and build specific integrations, which give you less freedom and dependencies towards 3rd parties.
As JRiver is doing an awesome job delivering/handling AV content, people want to stick with it. However the market is shifting to streaming, not to physical media.
People that bought a license request for an integration of Qobuz into their preferred software. As JRiver is in the top 3, I expect that JRiver want to stay there.
Some new innovations will not harm that position.
And maybe it's time to review the business plan as this topic keeps coming back and competitors did the integration already.
