Firstly, this blog is mostly SEO spam and is probably one of the worst written articles I've ever seen. The article itself is more keywords than content. Even the headline is garbage, persisting after reboots is a normal feature of almost all most malware types, including rootkits. In fact, I'd say a lot of cybersecurity blogs are like this, hyping up mundane malware that presents no special threat for the clicks.
But I'll break this down anyways.
The first bit about the dynamic linker, means doing things like restricting the files an app has access to, in order to prevent manipulation of how code libraries and modules are loaded, in order to prevent the injection of a malicious library. This can be done within the system, and often is by default, like how sudo refuses to load libraries it doesn't like.
The second bit is literally just recommending you require a password to do admin things. Of course, there's a lot more nuance to it. Access controls, controlling what user on a system has access to what can become a lot more fine grained, but for the kinds of malware that these articles report on, an admin password will stop them.
Here's my main argument for more private services (I try to make all my arguments short).
According to a study done by proton, a single company makes a minimum of $200 dollars off of each person, each year. Of course, they probably gain more money via clandestine deals or the government buying data directly to get around the 4th amendment.
But that money, doesn't go solely to the companies dedicated to collecting data, or those parts of other companies. It goes to lobbying the government to strip away privacy further.
And then I have two endings, depending on the situation:
Of course, I recognize that in today's connected world, I can't get privacy unless I go live in the woods. But I can decrease the amount of money companies make off my data, which I do like.
Organizations like the EFF, lobby on the other side, for more privacy for us. But they are opposed by when massive companies like google also lobby. So when I deny google $100, that's money they can't use to lobby anymore. Rather than thinking of it as denying google money, think of it as making a donation to the EFF, that they use to ensure our rights are in place.
