alt Hacker NewsRandom anecdotes like this don't equate to "company juicing their numbers". You need much stronger evidence than that to make such an assertion. There are legal and financial ramifications for lying, companies are audited, there are official forms and documents that public companies must file. Of course a company can lie on those forms, but in the case of a company like Google you need extraordinary, factual evidence to make claims like "they've been juicing their numbers".
You basically have to say, everyone from the CEO/CFO, to the auditors, the financial analysts, the legal team, and all the way down are all lying and this random guy on Twitter is telling the truth. Sorry, not buying it.

I don’t interpret “juicing” to imply illegal.
No one in Google is lying. If what the person in the Twitter post says is true, then everyone at Google is telling the truth, and so is OP.
And given all the replies to that post on Twitter, it sounds like it's true.
Juicing is not the same as lying. Did you read the post?
See the replies to that tweet. I agree, one swallow does not a spring make; but here there's a pattern. Ask anybody who does search advertising, and you'll hear the same story too many times for it to just be a coincidence.
Most people don't know this, but the Search Advertising auction is a black box. The advertiser just specifies a bid (the maximum they're willing to pay for a click); and the search engine promises that they will not pay more than that.
Here's a trick that Search Engines may (or may not, I plead the Fifth) use: the price an advertiser "i" who bid "bid_i" pays is bid_(i+1) * pctr_(i+1) / pctr_i where "pctr_(i+1)" is the predicted probability of click (pCTR) on the next lower ad; "pctr_i" is the predicted probability of click on the current ad.
Guess who calculates the pCTR? The Engine! In theory, if their pCTR calculations were 100% accurate, all advertisers would pay the minimum bid (which is typically $0.01)! Clearly, this is not desirable. So Engines juice the revenue by tweaking these pCTR values. Talk to anybody who works on auction mechanisms at a search engine, and you'll hear stories of how they tweaked these pCTR values.
