Clearly the Russians attempted to meddle in the U.S. political and election processes - just as they’ve attempted pretty continuously over the past century. Many other countries do so as well.
What is dubious is whether it was ever more than background noise during this election, and a bit of shock that it was just chaos instead of heavily weighted towards Democrats as their perpetual proxies.
Personally, I think if you even use the term “meddle” you’ve already bought into this Russian hoax conspiracy. I’m sure that “meddle” is not a legal category, and even as an issue of foreign affairs, it’s not something that’s ever been cited as a big issue before. We’re a massive country with a very long, deep and broad democratic process; I don’t accept that any other country can “meddle” in our elections, without somehow directly accessing our voting machinery, and no one has said that they did that. Did they try to “influence” our elections? Yes, probably, and so what? It’s not illegal, nor is it particularly improper. I trust Americans to wade through all of the different “influences” out there and make the right choice for the best interests of the country.
