Did Elon mention what this "Controversial" Announcement is in the shareholder meeting?

Didn't have time to watch it yet, but here is my guess.
Elon Musk is passionate about technology and
doing the right thing, more than money and power in itself. He already made enough money to live comfortably, very comfortably, to never need to work at all, yet he invested it all into going up against what is wrong. He is smart, he can see the solution, and he has the power to change the world. He already did, but this is only the beginning.
There is more to this world than money. Like making a dent in the universe, as another great innovator said, who unfortunately had to leave us a bit prematurely.
Opening up for the TM battery technology, the part of it which
controls temperature and charging of the battery, is
essential for other car makers to be successful with EVs without range extending. Fast charging, combined with safe and efficient battery handling, is vital to a technology where the
most critical part is energy storage. The electric drivetrain and everything else about the electric car is piece of cake and beats the pants off ICEs - but the weight, cost and efficiency of the batteries, is what is so challenging to solve.
Elon showed us it can be done, and I think he is going to reveal very soon, a way to
share this technology.
He is
not going to give it away for free, and he is
not going to dismiss the patent entirely, nor make it public domain / open source. But he is going to make it so
cheap to license it that it will be a no-brainer for other EV companies to use it.
Elon really wants EVs to succeed. He is not interested in having the entire automobile industry against him, he just wants us to stop burning fossil fuels, and start using safe and clean energy. And then, on the side, he burns just a little to propel some rockets into space, but that's another purpose - an exit plan for the human race, eventually, if we fail to save Planet Earth for human sustainability.
The real enemy here is not cars as such, but the way we fuel them. It is much more a
threat to oil companies, rather than auto makers. Imagine if there was only one brand of EV to choose from, because it was the only one which was really good? Elon has shown time and time again, he is really fair an not only a respectful gentleman, but also sincerely looking at the benefit for all, not just him or the companies he is involved in.
One example of the opposite is from Ford Motor Company. They hold a patent of heating the windshield of a car with electric wires inside the glass, which is great especially where there is a cold climate. But you don't see that in other cars, including Tesla Motors products, as Ford has the patent to do this exclusively. And they are not likely to share it with others, so if you want electric windscreen in your car - you are stuck with a Ford. Batteries in an EV is a leap more essential than a heated windshield, but it's the same principle.
After cars, buses, trucks and trains, I think the next one up is
powering of buildings. Heating, cooling, hot water, fridge/freezer, cooking - all that. Along with the transportation sector, domestic energy use is one of the largest users of energy consumption. And finally,
industrial production, which also has a huge potential to cut fossil fuel burning. Not an efficiency adjustment, but a real, significant shift of technology, into
avoiding burning stuff.
OK, this post became a little longer than I intended, almost like a blog entry. A little bit more than two cents worth
