Hi There!
Unfortunately, as both Ben and Pau are mentioning, this absurd practice is still hanging around the web. While it's very unlikely the stuffed footer is actually helping this competitor to achieve high rankings, it is aggravating to think it isn't preventing them, either.
Your post doesn't mention whether this is actually a business model with physical local offices or is fully virtual, but what I have seen in cases like these is that big brands tend to get away with a great deal of stuff I would never recommend to a smaller brand. It begs the question: how can we explain this phenomenon?
In the past, I've seen folks asserting that Google is soft on big brands. There could be some truth in this, but we've all seen Google take a massive whack at big brand practices with various updates, so that really makes this an unsatisfying assertion.
Another guess is that big brands have built enough supporting authority to make them appear immune to the consequences of bad practices. In other words, they've achieved a level of power in the SERPs (via thousands of links, mentions, reviews, reams of content, etc.) that enables them to overcome minor penalties from bad practices. This could be closer to the truth, but again, isn't fully satisfactory.
And, finally, there's the concept of Google being somewhat asleep at the wheel when it comes to enforcing guidelines and standards, and whether or not that's kind of excusable given the size of the Internet. They can't catch everything. I can see this in this light, but at the same time, don't consider Google to have taken a proactive stance on accepting public reporting of bad practices. Rather, they take the approach of releasing periodic updates which are supposed to algorithmically detect foul play and penalize or filter it. Google is very tied to the ideas of big data and machine intelligence. So far, it's been an interesting journey with Google on this, but it is what has lead to cases exactly like the one you're seeing - with something egregiously unhelpful to human users being allowed to sit apparently unpunished on a website that outranks you, even when you are trying to play a fairer game by the rules.
In cases like this, your only real option is to hang onto the hope that your competitor will be the subject of an update, at some point in the future, that will lessen the rewards they are receiving in the face of bad practices. Until then, it's heads down, working hard on what you can do, with a rigorous focus on what you can control.
