I do not think that the user above you is being brigaded by GrapheneOS.

Look into their history to see if they might've said to see if there was anything in their "most controversial" that could elicit a retaliation, and I found nothing.

I did find them often strongly saying unpopular opinions (or sidestepping a question), which people then downvote, and them sometime blaming the downvotes on outside actors.

"I didn't say something that wasn't true or not well received, I am clearly being attacked!!!"'

I'll copy the comment you are replying to so it can't go away:

I will go the opposite route here, and tell people to instead make an exception for certain things, and never go for cheap unknown brands.

highly reputed Oxymeter in medical establishment (do not buy inaccurate smartwatches, Apple is 20x ripoff and still subpar)
Victorinox for Swiss army knife
Victorinox or Leatherman for multitool
reputed branded batteries (Maxell, Duracell, Sanyo, Sony, Eneloop et al)
reputed battery/device chargers
PSU/SMPS and UPS for computer (APC, Emerson, Schneider and other brands) reputed brand watches (Casio, Citizen, Seiko have affordable BIFL options)
ThinkPad for laptop (user repairability, third party parts, open schematics)
Levis for jeans, they are almost BIFL
a good weighing machine for kitchen/home use
a good mixer grinder WITH safety lock (atleast 750W)
quality stationery pen, mechanical pencil, leads, eraser and other items (Uni, Pentel, Sakura, Staedtler et al, refer to JetPens website)
Edit: fuck you GrapheneOS, for almost 2 months now, they are mass downvoting my comments, and doing voting manipulation, also abusing federation

Reasons people might downvote:

• They are not answering the question that was asked
• They give lots of brands/products that people may disagree are high-quality.
• They recommend products that are outdated
• They gave a website that people should buy from (which may be seen as spammy)

Reasons people are probably not downvoting:

• They are GrapheneOS

he told people to buy cheap ass china phones and run some adb commands to disable google stuff, instead of buying a pixel and installing graphene or calyx
