Are streaming platforms trading tv-shows between each other?

As of January 1st the popular sitcom, Friends, is no longer available on Netflix and The Office (US) has been removed from HBO. (This might only be the case in Denmark, I haven't tried a VPN)

But you can still watch these shows albeit on the other platform, meaning you will now have to change your subscription from Netflix to HBO if, say, you wanted to keep being able to watch Friends.

Could this be a beginning of streaming platforms 'trading' tv-shows with each other and would this be a viable strategy to outperform services like Disney+ who has made most of it's content in-house and seen much success through 2020?

With a method like this these streaming platforms will be doubling down on their own content. Netflix has been doing this for some time, throwing money at their Netflix Originals, but their budget is way above most other streaming platforms.

Trading tv-shows will undoubtedly affect churn rates and original content will determine the future of platforms.
I could see this working out.

Imagine:

Platforms have their own original content which is what they will be subscribed to for. Examples: Netflix's Stranger Things and HBO's Game of Thrones. Besides this, platforms will have a sort of rotation of sideshows, enter Friends, The Office, HIMYM...

These sideshows would be a sort of added bonus to the platform rotating every couple of months and be there to keep the subscribers subscribed during new tv-show droughts/between seasons. This idea would mean while Netflix has Friends on rotation HBO will have something else etc.

While this may sound risky, this may be the way for streaming platforms to cement themselves in the space. If sideshows are going to be available only for certain periods every year, the Originals will dictate the churn rate.

This means the moat of a streaming platform will be decided by it's original content and therefore the market will be much harder to break into, leaving market shares to the big players in the space.

We already see some platforms going all in on their own content. In some years these might be the only ones left.
