If "Jump the shark" is supposed to describe a change for the worst, personally, I'd say that most of their changes in the last 20 years have been largely positive. They are making theses changes to adapt to the changing world and are slowly becoming a streamlined religion:
- Don't count hours for regular folks
- Now produce a fraction of magazines compared to before
- Beards
- improved policy to address pedophilia (its not perfect, but it is better then before)
- Accepting fractions of blood (before it was none at all)
- Accepting military service if it is in none military settings (hospital, etc)
- They don't bother parents who talk to their disfellowshipped kids as they did before
- Vasectomies aren't a big deal anymore
Sure, there is room for significant improvement, in particular, they should:
- Get rid of disfellowshipping
- Let the blood doctrine to the conscience of their folks.
As for real "Jump the shark" changes, I can think of these two major ones:
1) Reducing the Ministry school to a shadow of what it was. It was basically a free "Toast Master Club" that everyone could take a part of.
2) The quality of the text used when writing articles. Now, its written for a 6 grade level and simply feels dumb.
These last two were hugely beneficial to me and I'm grateful that the cult gave me at least that. And now its gone.
