That's incorrect for these style of calls. The help is more akin to marketing - the company is arguing that they are doing better than the analyst thinks, and the analyst's company is offering their help to explain that to them and to other analysts.
That isn't what stock market manipulation[1] means.
Market manipulation may involve techniques including:
Spreading false or misleading information about a company;
Engaging in a series of transactions to make a security appear more actively traded; and
Rigging quotes, prices, or trades to make it look like there is more or less demand for a security than is the case.
Presenting real information in a way that makes it more clear to investors is absolutely not market manipulation, and no interested party would ever claim otherwise.
