The radar you're talking about is a pulse-doppler radar. It doesn't see things the same way your eyes (or a synthetic-aperture radar for example) do and it's not down to filters. A P-D radar observes and measures the Doppler effect which only occurs when the object is moving and determines the contact's velocity, heading and altitude based on that. A jet flying vertically at 0 GS would probably be detectable, although this would be difficult since, as you said, it's not moving directly towards or away from the radar.

Re-rendering 4k videos (or of any other quality fwiw) with ads included would probably incur more electricity costs than they could ever make through the ads. TV could afford to do this since they transmit the same program and the same ads to everyone. Youtube targets them per user, so they'd need to render the same video, in high quality, every time any user clicks on it.

when are they gonna learn that any client-side restriction or hindrance can and will be defeated? sleep(5000) is kinda like them throwing a fit, not actually trying to punish anyone. obviously we'll find a way to avoid waiting the 5s, do they think we'll just give up?

what is it with chinese-made games and extremely invasive anticheats

hijacking update channels is a possibility but as the other guy said very unlikely

I don't think it's paranoid to not want any intermediary to know what you're talking about, even if all you're talking about is innocuous things like groceries.

Besides, they don't have to "waste time" on anything. They've got computers to collect it all.

Of course, like you said, Signal or Matrix are potential solutions for that, but you still need to get both sides to agree on using them. SMS have the advantage that everyone has a phone number and can thus use them. Upgrading to RCS will secure this insecure-yet-very-popular medium.

Is there zero risk or do you think there is zero risk? Text messages can absolutely be intercepted by your service provider

Yeah, he learned it from the Russians

Because as we all know Chinese companies never collect people's data

Why not both? Digital is obviously better but analog is painfully simple hence it'll probably be the medium used for transmitting emergency alerts

Stop trusting your messaging platform and use this other messaging platform! Matrix can be less secure than Signal if used improperly
