I like Techlore (https://www.techlore.tech/videos if you don't know) and I usually regard them as one of the most impartial and most trustworthy Youtubers out there. But for the past few months, I couldn't help noticing their somewhat heavy bias towards some of their video sponsor. Still, everybody has to eat right?
This time though, it looks like Synology flew them over to Taiwan, and if you watch their video at the event, it's wall-to-wall Synology shilling. I'm really disappointed.
I think you have to be exceptionally strong to resist this sort of thing. You can justify sponsorship in a hundred ways - not least to yourself. But in every case, it changes everything. That, of course, is why companies spend money influencing the influencers.
Buyer beware, as always.
