They are, or rather were. For most of the world, especially in Europe, liberalism means/meant socially liberal, i.e. left wing - based on personal freedom from imposition of others’ values on their personal and social lives. However, in America liberal has (relatively recently, as in 2000’s) become synonymous with neoliberal ideology, which is absolutely not left wing in any traditional sense, focusing on ‘small government’ and freedom of the markets—I guess because pronouncing two extra syllables is too much effort? Idk.
With the internet this peculiar usage has recently (as in the last 5-10 years) started leaking out of America and is being used in this confusing and ambiguous manner.
To be fair though, the Overton window has shifted so far right now that liberal (i.e. left of the nominal centre) shares much of the same space as neoliberal. See New Labour, and the current Labour government.
Edit: Deleted a paragraph that in retrospect was unnecessarily negative.
