Network 23 has possibly mistakenly provided advice and information that is inaccurate.
Some SSD brands do not require TRIM and some like OWC don't even recommend it because their SSDs have their own similar routines.
Apple Should have Trim enabled (as it does with SMART and other technologies) if the device supports it regardless if Apple sells the SSD or not.
For some unpublished reason that harms customers, Apple and 3rd party vendors of SSDs are confusing the public on this issue. Including OWC by blogging that their SSDs do not require Trim.
As usual practice at OWC they circumvent the whole problem (Apple's) by either using or emulating the same vendor chipsets Apple uses and thus OSX automatically has Trim enabled by default
OWC needs trim and they get it!
OWC please do not lie to me, thank you! (love their products too btw)
SSDs will work with Yosemite, the only thing that won't work is enabling third-party TRIM support. The SSD will boot and the SSD will work and it will be fast; having TRIM enabled is not even remotely a requirement. TRIM is just a housekeeping routine that is generally thought to be desired, but there's even debate on that.
There is no debate, there is FUD as written above Apple and other Vendors are misleading the public and for anyone wanting to get a clear understanding on this topic google Kent Smith of LSI
Trim is designed to interoperate with the standard Garbage Collection implemented by all vendors. An easy explanation is that Trim is the OS' side of targeting what garbage to collect. It's just that simple and it completely enhances the longevity as well as the performance for your SSD. That's why a hardware vendor like Apple has discovered a means to cripple competitor products (on their own platform for godsakes...) and thus harm you the Apple Customer.
This is truly a counterproductive move by Apple, and frankly appears to me the harbinger of more "Insanely Insane" things to come from the Company...
Good luck Guys!

Parting thoughts....
"Keeping your SSD TRIM
A number of years ago, the storage industry got together and developed a solution between the OS and the SSD by creating a new SATA command called TRIM. It is not a command that forces the SSD to immediately erase data like some people believe. Actually the TRIM command can be thought of as a message from the OS about what previously used addresses on the SSD are no longer holding valid data. The SSD takes those addresses and updates its own internal map of its flash memory to mark those locations as invalid. With this information, the SSD no longer moves that invalid data during the GC process, eliminating wasted time rewriting invalid data to new flash pages. It also reduces the number of write cycles on the flash, increasing the SSDs endurance. Another benefit of the TRIM command is that more space is available for dynamic OP."
