I cancelled my evernote subscription because it is too slow to start up. If I need to access a note on my phone, I don't want it to take perceived time, because then I have to go through the effort of remembering what I am trying to write.
I have switched to Apple notes, which seem to get this.
“Oh, that’ll load in the blink of an eye! Only as much latency as the blink of an eye!” etc
It was damn frustrating to try and explain to these clowns that things look like crap if you pile up 2+ blinks of an eye on top of them. In the case of VR, even one “blink of an eye” is about 10x too much delay
So ad blocking makes everything faster!
How does this allow for header bidding? Anything needed could be done in page or with a connection that delays the response until some condition is met.
The browser adding an artificial delay seems like it's just a way for the browser to control the process, and when the browser is controlled by an ad network, that makes me very suspicious as to the motives for an artificial delay.
These tactics, similar to deliberately introduced incompatibilities or performance differences, are old hat. For example, through the 90's, third party software for Windows never ran as smoothly as software issued by Microsoft. It was not the same "user experience". So long as this sort of conduct remains "legal", these companies interpret that as permission to engage in it.
