These are very poor examples. These are all revenue generating companies that have been around a long time with revenue that helps stabilize the SP and large market caps trading in the US. (Time Warner, CBS, etc.. )
Lets see an example of the percentage of reverse splits that are successful on the venture exchange? It is well known that most do not turn out great, and i have witnessed it 90% of the time so no one can convince me otherwise. POET is in a better position financially and with much more promise so maybe they will be the 10%. But these examples cannot be used to compare a pre-revenue company like POET.
