Buy one used to not financially support them. GrapheneOS only supports Pixel phones as they are the only ones which meet the security requirements.

I bought my Pixel 9 refurbished (as new).

Refurbished is a thing. So is 

I bought mine from Telus .. so i would think Telus gave them the money a long time ago for said phone and i'm just giving Telus back their money .. now i'm not giving money or data to anyone.

A while ago they announced they were planning a collaboration with a big phone brand

Nothing else meets the secuirty requirements and they don't want to comprimise.

I initially considered that, but in the end I just bit the bullet and got one 2 weeks ago.

My thought is with the current trend of PC hardware prices, I didn't want to wait to see how it affects phone prices.

At the same time, I do not know if the collaborative phone between GOS and the manufacturer will be something I like. The current Pixel 10 phone is already bigger than what I ultimately prefer and I think it's more probable the new phone will be phablet sized.

Blame literally every other hardware manufacturer for not implementing encryption enclaves correctly.

TL;DR The above commenter is spreading FUD. GOS will work fine and allow sideloading.

Stop spreading FUD. Google kills sideloading on Google certified ROMs. Being Google certified doesn't mean you have more features than ROMs which aren't certified. Only Google certified ROMs lose the ability to sideload and have to adhere to all Google Play policies. Meaning GOS loses its certified status but doesn't lose the ability to sideload. The only way in which GOS might be coerced to disable sideloading is if Google pushes these changes upstream to the AOSP and even then forking is always an option. Also when has Google ever hinted at disabling flashing custom ROMs? It might be right down their alley but I wouldn't make such claims without citing sources.

Just as a side note: Android ≠ AOSP. This is relevant as many people misunderstand the news they read. When Google changes Android (Google's proprietary AOSP "distro") it doesn't necessarily mean that changes are coming to the AOSP or GOS which is also an AOSP "distro".

Reading through this forum thread is recommended.

Fairphone 6. Google can suck it. As long as people support the company, competition is coming. Hopefully, they have the resources to keep on going after Google shits on everyone.

That's precisely my biggest problem with GrapheneOS

This betrays a deep level of tech illiteracy

The level of security, of privacy and of granular control of those does not come even close to what GrapheneOS brings to the table. Additionally Iodè and /e/OS have some noise going on with not being private at all. And all of them, except LineageOS (some times) have long delays with security patches.

/e/OS uses OpenAI for voice-to-text. Iodé has closed source components (trust me bro?). What do they claim? "some protection is better than none". In security that is ridiculous.

Then there is choosing between Microg vs actual sandboxed Google Play Services (which you don't need to have at all on GrapheneOS if you don't want to).

/e/OS signs their OS with Google test keys instead of their own keys.

Unconfirmed, but concerning is the claims of ties of those 2 (Iodé and /e/OS) with the French government, not unlike Chinese companies with the CCP.

Choosing LineageOS, or even CalyxOS are options I would consider if I wasn't willing or able to get a Pixel device, but Iodé and /e/OS are absolute 'no' in my book. Too many holes, too pragmatic (and I'm trying to be nice using that word) for my taste.

Ironic but true
