The point was that Samsung, despite what you mentioned, put out phones like the Samsung Galaxy S1 with their own home-made filesystems RFS.
The performance of RFS once the filesystem became somewhat populated was horrible and was the one single bottleneck for every single operation on the phone. It made otherwise top-end hardware (for the time) unbearably slow, bordering on useless.
Think 10 seconds lag to go back from an email to the email-listing. Those were real delays. Real problems. Caused by RFS.
I have personally experienced people thank me for giving them "a completely new phone" (quote end) when I rooted the phones and converted all RFS-partitions to EXT4. All those problems went away and you finally got the phone you thought you bought in the first place.
Given this, touching any filesystem by Samsung is something I will give serious second thoughts.
To give Samsung credit, they ditched RFS entirely for their second line of Galaxy S phones. The Galaxy S2 used standard Linux filesystems and RFS has yet to resurface anywhere near civilized folks.
