Why was TrueCrypt Discontinued

I know this happened a long time ago, but I always wanted to ask this to a professional: Why was TrueCrypt Discontinued? Is it related to this: FBI hackers fail to crack TrueCrypt? And what is the best option, without backdoors, currently available?

HMAC-Ripemd-160 in TrueCrypt

I'm wondering if it is still secure. I know TrueCrypt closed its doors but I continue using it because the cryptoaudit didn't find any huge bugs or security issues in TrueCrypt. But I have a bad feeling about Brute Force and Ripemd-160. I've read…

Why mounting/dismounting an encrypted file container takes only a few seconds?

When the encrypted file container contains 100000 files and 500 GB of data, all of them must be decrypted/encrypted when the container is mounted/dismounted. How can Truecrypt/Veracrypt perform this within a few seconds?
