WhatsApp was build upon XMPP protocol. You can look into XMPP clients.
Besides that WhatsApp is not the way to communicate anyway. Normies use it because it is put up on their face and considered to be widely acceptable among them, while rhey don't understand how privacy invading it is.
Technically NFT, a token is linked/owned by a wallet address. Which you cannot pirate/dublicate.
But in case of nft images, those tokens are linked to an image on ipfs through dapps, which you can download. But there is legal uncertainty about these images.
I started using it on a daily bases since I switched to Linux. The distro I use as daily driver and other large projects have their support team on IRC.
It is much much better than posting on forums. You get instant response.
This is quite thought provoking. I never thought in this manner.
You question is in two parts.
Don't bother using collection. When I made one for personal use, the fucker downloaded some outdated version of the mod. I started using my download history to keep in check what I've download and used vortex to handle the installation.
In general, simply dropping the mods in the correct location installs the mod, but few mods (like in case of Cyberpunk 2077, Redmod) get compiled to show up as game files, which might complicated the proceduce but I think its possible.
I don't know what you mean by downloading one by one. Nexus does lets you download multiple mods at a time when done manually. When installing mods with Vortex, it downloads it, installs it, verifies it and looks for the next in the queue.
But if you are still keen to use more bandwidth, perhaps try using tor, see if Nexus allows it? I haven't checked on my end since I never really downloaded huge mods.
I've tested Cyberpunk 2077 on Ubuntu (not my daily driver) and it works like you're playing on windows. Only downside is that you can't use ray tracing since Nvidia kept that tech proprietary and exclusive to windows for now.
See, Linux doesn't fully supports nvidia gpu, but still I'm having a great experience.
What are you talking about? Ofcourse everyone should worry about backdoors and other vulnerabilities. But I'm sceptical if bitlocker is the right solution.
On a serious note I use a lot of tools to circumvent those vulnerabilities.
Mullvad or Proton
