I'll bite on this topic simply because I don't think there are enough people who don't think it's a big deal. You get some people smugly sitting back, watching other people react with outrage or disgust. You get others perplexed by the whole thing. My reaction is "eh."
The temple ordinances are sacred, not secret, as has been said many times before. They have been available for reading in their entirety for a very long time. The Church has not to my knowledge been overly concerned with temple security. Anyone with cunning, patience and will could sneak in. Additionally, anyone (member or not) who is curious about the temple can attend an open house before it is dedicated and have a great many questions answered without resorting to subterfuge. In fact, in some countries (such as Germany), the temple and its grounds can be annexed and used by the government at any time.
None of it matters to me. No amount of discussion or verbatim quotation can come close to touching on the actual ceremony. A surprising amount of the temple ceremony can be shared and discussed without breaking covenants (per Boyd K. Packers The Holy Temple) and there are very few parts that are not discussed therein. Much of the temple ceremony can be found in scripture, if you know what to look for. True, I have made covenants not to share certain aspects of the temple ceremony outside of certain areas of the temple itself, and it matters to me not in the least that others have broken their covenants to do so.
Likewise, it matters to me not in the least that some members are part of the cast, and intend to be next year. That is their issue with God, and I am no judge of it, even if I wanted to be.
So, I don't really care what other people do with things I hold sacred. They cannot tarnish my experiences in the temple no matter how they try. They can't even understand them, should they recite the ceremonies in their entirety. That is good enough for me.
I know what I have experienced in the temple. I know how I have been able to draw closer to God, better understand His love for me, and my role in life. No other place has been a sanctuary for me in the way the temple has. It is simply a natural yet infinitely beautiful part of my progression towards God. In the temple, I have drunk deeply of the Spirit. I have worshiped and been befriended by my God. What can compare?
