You're quoting the Ukrainian Prime Minister
And he was quoting US intelligence.

We assess that Flight MH17 was likely downed by a SA-11 surface-to-air missile from separatist-controlled territory in eastern Ukraine. We base this judgment on several factors.
Oh wait, it's not even "most likely", but just "likely". Thanks.
Why one earth are you ignoring this stuff?
I'm not ignoring it, but posts in "social media" are simply not evidence.
OSCE themselves also just said something completely different than mass media did.
I will quote it again, youtube link is a few pages back. It's BBC world, so hopefully not infiltrated by Russia.
"whenever we said we wanted to go to the site ... they let us ..."
...
"they've done some work in terms of perimeter security for us ... because there are a lot of turmoils here ..."
They didn't say "well after 2 days we were let to the site", no - they said "whenever we wanted to go to the site, we were let there"
Still OSCE themselves are not absolutely trustworthy anymore. In May a group of effectively western military spies were held by the rebels and at least in my country mass media called them "OSCE observers" from beginning to end, which simply wasn't true. And this was done everywhere. Television. Print. Internet. But fact is that those weren't people from the OSCE and OSCE themselves didn't have a problem with that. There were a few reports in the end saying that "oh well, it wasn't true, they were actually military inspectors, not related with OSCE, but who gives a shit". That's the definition of fact-twisting and propaganda, which is acceptable from mass media, but OSCE should have done something right at the start of it, but they didn't.
