Here's the thing: Sure. "Old people" exist. They are often in charge of things. Many of them read blogs and surf the internet. Do you really, honestly think that somebody who surfs the internet and reads blogs, especially blogs about video encoding, won't be aware of the current meaning of the word?

Honestly?

You see the word "sucks", in the context of something not being very good, everywhere. Literally everywhere. I bet that if you googled any tech-related keyword, somewhere in the first ten results, "sucks" would be employed in the context of "is not so good".

My point is this: People that read that blog post _will_ know what "sucks" means in that context and will not infer anything sexual from it - and even if they did, it's hardly the end of the world. Surely nobody who spends any reasonable amount of time reading blogs about video encoding will be in the slightest offended by fellatio. After all, "old people" are no different to "young people" except they have more experiences under their belt (hyuk hyuk).
