perestroika

If conservative means "cautious and wary of unexpected results", "disillusioned with methods that we tried and failed with" or maybe even "equipped with experience of successful and failed cooperation with various sorts of people", then yes. Already before age 50, I'm spoiled with various good and bad experiences. I cannot exclude that as my tendency to explore decreases (psychology tends to affirm this trend), I may get prejudiced too. I may have to figure out something to counter it.

But if conservative means that I suddenly don't want a society with equality and without hierarchy, then - nope.

Speculation has it that either "Palyantsia" (small turbojet drone) or "Neptun" (sizable cruise missile, antiship with ground strike capability) were used. Since part of the Russian facility was hardened and underground, I would ordinarily favour the hypothesis of "Neptun", but it's supposed to be out of their range and the videos recorded over Russia featured a turbojet sound and the video you linked has a small explosion (this would fit "Palyantsia", since it's small).

As a happy user of Signal (no bugs or incidents from my viewpoint), I regardless chime in to say a word for decentralization. :)

Signal is centralized:

• there is a single Signal implementation, with a single developing entity
• you have to install its mobile version before you may run the desktop version

There exist protocols like Tox which go a step beyond Signal and offer more freedom -> have multiple clients from diverse makers (some of them unstable), don't have centralized registration, and don't rely on servers to distribute messages - only to distribute contact information.

In the grand comparison table of protocols (not clients), Tox is among the few lines that's all green (Signal has one red square).

They can shoot their foot with a grenade launcher next. I'm already out of range.

If they overcome / disable ad blocking, they will lose browser market share - and people don't design websites for marginal browsers with exotic features.
