Is there any reason in particular you think this? Sony only removed the feature, citing "security concerns" mere months after George Hotz released the exploit. They would later go on to sue him. https://blog.playstation.com/archive/2010/03/29/ps3-firmware...
On the other hand, the Ps3 clusters were around since basically the console's launch. Additionally, the console had been selling at a profit, at least in the US, by 2009, before they removed the other os feature.
All this happened 16 years ago. If you're curious about stuff that has happened so recently, you can research it online.
I think this because it was all over the tech news outlets at the time that the primary reason was due to Sony losing money because of console hardware being sold below the price of the components themselves.
A company press release is not necessarily the be-all end-all full story when it comes to justifying something extremely unpopular with their customer base.
